* SQL JSON functionsAndrew Dunstan2022-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | This Patch introduces three SQL standard JSON functions: JSON() (incorrectly mentioned in my commit message for f4fb45d15c) JSON_SCALAR() JSON_SERIALIZE() JSON() produces json values from text, bytea, json or jsonb values, and has facilitites for handling duplicate keys. JSON_SCALAR() produces a json value from any scalar sql value, including json and jsonb. JSON_SERIALIZE() produces text or bytea from input which containis or represents json or jsonb; For the most part these functions don't add any significant new capabilities, but they will be of use to users wanting standard compliant JSON handling.

* SQL/JSON query functionsAndrew Dunstan2022-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces the SQL/JSON functions for querying JSON data using jsonpath expressions. The functions are: JSON_EXISTS() JSON_QUERY() JSON_VALUE() All of these functions only operate on jsonb. The workaround for now is to cast the argument to jsonb. JSON_EXISTS() tests if the jsonpath expression applied to the jsonb value yields any values. JSON_VALUE() must return a single value, and an error occurs if it tries to return multiple values. JSON_QUERY() must return a json object or array, and there are various WRAPPER options for handling scalar or multi-value results. Both these functions have options for handling EMPTY and ERROR conditions.

* SQL/JSON constructorsAndrew Dunstan2022-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the SQL/JSON standard constructors for JSON: JSON() JSON_ARRAY() JSON_ARRAYAGG() JSON_OBJECT() JSON_OBJECTAGG() For the most part these functions provide facilities that mimic existing json/jsonb functions. However, they also offer some useful additional functionality. In addition to text input, the JSON() function accepts bytea input, which it will decode and constuct a json value from. The other functions provide useful options for handling duplicate keys and null values. This series of patches will be followed by a consolidated documentation patch.

* Introduce "anycompatible" family of polymorphic types.Tom Lane2020-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the pseudo-types anycompatible, anycompatiblearray, anycompatiblenonarray, and anycompatiblerange. They work much like anyelement, anyarray, anynonarray, and anyrange respectively, except that the actual input values need not match precisely in type. Instead, if we can find a common supertype (using the same rules as for UNION/CASE type resolution), then the parser automatically promotes the input values to that type. For example, "myfunc(anycompatible, anycompatible)" can match a call with one integer and one bigint argument, with the integer automatically promoted to bigint. With anyelement in the definition, the user would have had to cast the integer explicitly. The new types also provide a second, independent set of type variables for function matching; thus with "myfunc(anyelement, anyelement, anycompatible) returns anycompatible" the first two arguments are constrained to be the same type, but the third can be some other type, and the result has the type of the third argument. The need for more than one set of type variables was foreseen back when we first invented the polymorphic types, but we never did anything about it.

* Introduce macros for typalign and typstorage constants.Tom Lane2020-03-04
| | | | | | | | | | | | | | | | | | | | | Our usual practice for "poor man's enum" catalog columns is to define macros for the possible values and use those, not literal constants, in C code. But for some reason lost in the mists of time, this was never done for typalign/attalign or typstorage/attstorage. It's never too late to make it better though, so let's do that. The reason I got interested in this right now is the need to duplicate some uses of the TYPSTORAGE constants in an upcoming ALTER TYPE patch. But in general, this sort of change aids greppability and readability, so it's a good idea even without any specific motivation. I may have missed a few places that could be converted, and it's even more likely that pending patches will re-introduce some hard-coded references. But that's not fatal --- there's no expectation that we'd actually change any of these values. We can clean up stragglers over time. Discussion: https://postgr.es/m/16457.1583189537@sss.pgh.pa.us
* Move jsonapi.c and jsonapi.h to src/common.Robert Haas2020-01-29

* Adjust pg_parse_json() so that it does not directly ereport().Robert Haas2020-01-27
| | | | | | | | | | | | | | | | | | | | | Instead, it now returns a value indicating either success or the type of error which occurred. The old behavior is still available by calling pg_parse_json_or_ereport(). If the new interface is used, an error can be thrown by passing the return value of pg_parse_json() to json_ereport_error(). pg_parse_json() can still elog() in can't-happen cases, but it seems like that issue is best handled separately. Adjust json_lex() and json_count_array_elements() to return an error code, too. This is all in preparation for making the backend's json parser available to frontend code.

* Allow datetime values in JsonbValueAlexander Korotkov2019-09-25
| | | | | | | | | | | | | | | | | | | | SQL/JSON standard allows manipulation with datetime values. So, it appears to be convinient to allow datetime values to be represented in JsonbValue struct. These datetime values are allowed for temporary representation only. During serialization datetime values are converted into strings. SQL/JSON requires writing timestamps with timezone in the same timezone offset as they were parsed. This is why we allow storage of timezone offset in JsonbValue struct. For the same reason timezone offset argument is added to JsonEncodeDateTime() function. Extracted from original patch by Nikita Glukhov, Teodor Sigaev, Oleg Bartunov. Revised by me.

* Partial implementation of SQL/JSON path languageAlexander Korotkov2019-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SQL 2016 standards among other things contains set of SQL/JSON features for JSON processing inside of relational database. The core of SQL/JSON is JSON path language, allowing access parts of JSON documents and make computations over them. This commit implements partial support JSON path language as separate datatype called "jsonpath". The implementation is partial because it's lacking datetime support and suppression of numeric errors. Missing features will be added later by separate commits. Support of SQL/JSON features requires implementation of separate nodes, and it will be considered in subsequent patches. This commit includes following set of plain functions, allowing to execute jsonpath over jsonb values: * jsonb_path_exists(jsonb, jsonpath[, jsonb, bool]), * jsonb_path_match(jsonb, jsonpath[, jsonb, bool]), * jsonb_path_query(jsonb, jsonpath[, jsonb, bool]), * jsonb_path_query_array(jsonb, jsonpath[, jsonb, bool]). * jsonb_path_query_first(jsonb, jsonpath[, jsonb, bool]). This commit also implements "jsonb @? jsonpath" and "jsonb @@ jsonpath", which are wrappers over jsonpath_exists(jsonb, jsonpath) and jsonpath_predicate(jsonb, jsonpath) correspondingly. These operators will have an index support (implemented in subsequent patches). Catversion bumped, to add new functions and operators. Code was written by Nikita Glukhov and Teodor Sigaev, revised by me. Documentation was written by Oleg Bartunov and Liudmila Mantrova. The work was inspired by Oleg Bartunov.

* Fix assorted compiler warnings seen in the buildfarm.Tom Lane2018-05-02
| | | | | | | | | | | | | | | | | Failure to use DatumGetFoo/FooGetDatum macros correctly, or at all, causes some warnings about sign conversion. This is just cosmetic at the moment but in principle it's a type violation, so clean up the instances I could find. autoprewarm.c and sharedfileset.c contained code that unportably assumed that pid_t is the same size as int. We've variously dealt with this by casting pid_t to int or to unsigned long for printing purposes; I went with the latter. Fix uninitialized-variable warning in RestoreGUCState. This is a live bug in some sense, but of no great significance given that nobody is very likely to care what "line number" is associated with a GUC that hasn't got a source file recorded.

* Make DatumGetFoo/PG_GETARG_FOO/PG_RETURN_FOO macro names more consistent.Tom Lane2017-09-18
| | | | | | | | | | | | | | | | | | | | | By project convention, these names should include "P" when dealing with a pointer type; that is, if the result of a GETARG macro is of type FOO *, it should be called PG_GETARG_FOO_P not just PG_GETARG_FOO. Some newer types such as JSONB and ranges had not followed the convention, and a number of contrib modules hadn't gotten that memo either. Rename the offending macros to improve consistency. In passing, fix a few places that thought PG_DETOAST_DATUM() returns a Datum; it does not, it returns "struct varlena *". Applying DatumGetPointer to that happens not to cause any bad effects today, but it's formally wrong. Also, adjust an ltree macro that was designed without any thought for what pgindent would do with it. This is all cosmetic and shouldn't have any impact on generated code.

* Phase 3 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Initial pgindent run with pg_bsd_indent version 2.0.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new indent version includes numerous fixes thanks to Piotr Stefaniak. The main changes visible in this commit are: * Nicer formatting of function-pointer declarations. * No longer unexpectedly removes spaces in expressions using casts, sizeof, or offsetof. * No longer wants to add a space in "struct structname *varname", as well as some similar cases for const- or volatile-qualified pointers. * Declarations using PG_USED_FOR_ASSERTS_ONLY are formatted more nicely. * Fixes bug where comments following declarations were sometimes placed with no space separating them from the code. * Fixes some odd decisions for comments following case labels. * Fixes some cases where comments following code were indented to less than the expected column 33. On the less good side, it now tends to put more whitespace around typedef names that are not listed in typedefs.list. This might encourage us to put more effort into typedef name collection; it's not really a bug in indent itself. There are more changes coming after this round, having to do with comment indentation and alignment of lines appearing within parentheses. I wanted to limit the size of the diffs to something that could be reviewed without one's eyes completely glazing over, so it seemed better to split up the changes as much as practical.

* Use wrappers of PG_DETOAST_DATUM_PACKED() more.Noah Misch2017-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | This makes almost all core code follow the policy introduced in the previous commit. Specific decisions: - Text search support functions with char* and length arguments, such as prsstart and lexize, may receive unaligned strings. I doubt maintainers of non-core text search code will notice. - Use plain VARDATA() on values detoasted or synthesized earlier in the same function. Use VARDATA_ANY() on varlenas sourced outside the function, even if they happen to always have four-byte headers. As an exception, retain the universal practice of using VARDATA() on return values of SendFunctionCall(). - Retain PG_GETARG_BYTEA_P() in pageinspect. (Page images are too large for a one-byte header, so this misses no optimization.) Sites that do not call get_page_from_raw() typically need the four-byte alignment. - For now, do not change btree_gist. Its use of four-byte headers in memory is partly entangled with storage of 4-byte headers inside GBT_VARKEY, on disk. - For now, do not change gtrgm_consistent() or gtrgm_distance(). They incorporate the varlena header into a cache, and there are multiple credible implementation strategies to consider.
