* Improve two comments related to a boolean DefElem's valueMichael Paquier2022-07-11
| | | | | | | | | | | | The original comments mentioned a "parameter" as something not defined in a fast-exit path to assume a true status. This is rather confusing as the parameter DefElem is defined, and the intention is to check if its value is defined. This improves both comments to mention the value assigned to the DefElem's value instead, so as future patches are able to catch the tweak if this code pattern gets copied around more.

* Add Boolean nodePeter Eisentraut2022-01-17
| | | | | | | | | | Before, SQL-level boolean constants were represented by a string with a cast, and internal Boolean values in DDL commands were usually represented by Integer nodes. This takes the place of both of these uses, making the intent clearer and having some amount of type safety.

* Rename value node fieldsPeter Eisentraut2022-01-14
| | | | | | | | | For the formerly-Value node types, rename the "val" field to a name specific to the node type, namely "ival", "fval", "sval", and "bsval". This makes some code clearer and catches mixups better.

* Remove Value node structPeter Eisentraut2021-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | The Value node struct is a weird construct. It is its own node type, but most of the time, it actually has a node type of Integer, Float, String, or BitString. As a consequence, the struct name and the node type don't match most of the time, and so it has to be treated specially a lot. There doesn't seem to be any value in the special construct. There is very little code that wants to accept all Value variants but nothing else (and even if it did, this doesn't provide any convenient way to check it), and most code wants either just one particular node type (usually String), or it accepts a broader set of node types besides just Value. This change removes the Value struct and node type and replaces them by separate Integer, Float, String, and BitString node types that are proper node types and structs of their own and behave mostly like normal node types. Also, this removes the T_Null node tag, which was previously also a possible variant of Value but wasn't actually used outside of the Value contained in A_Const. Replace that by an isnull field in A_Const.

* Improve reporting of "conflicting or redundant options" errors.Dean Rasheed2021-07-15
| | | | | | | | | | | | | | | | | | | | | When reporting "conflicting or redundant options" errors, try to ensure that errposition() is used, to help the user identify the offending option. Formerly, errposition() was invoked in less than 60% of cases. This patch raises that to over 90%, but there remain a few places where the ParseState is not readily available. Using errdetail() might improve the error in such cases, but that is left as a task for the future. Additionally, since this error is thrown from over 100 places in the codebase, introduce a dedicated function to throw it, reducing code duplication.

* 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.

* Generate fmgr prototypes automaticallyPeter Eisentraut2017-01-17
| | | | | | | | | | | | Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains prototypes for all functions registered in pg_proc.h. This avoids having to manually maintain these prototypes across a random variety of header files. It also automatically enforces a correct function signature, and since there are warnings about missing prototypes, it will detect functions that are defined but not registered in pg_proc.h (or otherwise used).

* Add location field to DefElemPeter Eisentraut2016-09-06
| | | | | | | | | | | | | | Add a location field to the DefElem struct, used to parse many utility commands. Update various error messages to supply error position information. To propogate the error position information in a more systematic way, create a ParseState in standard_ProcessUtility() and pass that to interested functions implementing the utility commands. This seems better than passing the query string and then reassembling a parse state ad hoc, which violates the encapsulation of the ParseState type.

* Allow aggregates to provide estimates of their transition state data size.Tom Lane2013-11-16
| | | | | | | | | | | | | | | | | | | | Formerly the planner had a hard-wired rule of thumb for guessing the amount of space consumed by an aggregate function's transition state data. This estimate is critical to deciding whether it's OK to use hash aggregation, and in many situations the built-in estimate isn't very good. This patch adds a column to pg_aggregate wherein a per-aggregate estimate can be provided, overriding the planner's default, and infrastructure for setting the column via CREATE AGGREGATE. It may be that additional smarts will be required in future, perhaps even a per-aggregate estimation function. But this is already a step forward. This is extracted from a larger patch to improve the performance of numeric and int8 aggregates. I (tgl) thought it was worth reviewing and committing this infrastructure separately. In this commit, all built-in aggregates are given aggtransspace = 0, so no behavior should change. Hadi Moshayedi, reviewed by Pavel Stehule and Tomas Vondra

* Define a new, more extensible syntax for COPY options.Tom Lane2009-09-21
| | | | | | | | | This is intentionally similar to the recently revised syntax for EXPLAIN options, ie, (name value, ...).

* Extend EXPLAIN to allow generic options to be specified.Tom Lane2009-07-26
| | | | | | | | | | | | | | | The original syntax made it difficult to add options without making them into reserved words. This change parenthesizes the options to avoid that problem, and makes provision for an explicit (and perhaps non-Boolean) value for each option. The original syntax is still supported, but only for the two original options ANALYZE and VERBOSE. As a test case, add a COSTS option that can suppress the planner cost estimates. This may be useful for including EXPLAIN output in the regression tests, which are otherwise unable to cope with cross-platform variations in cost estimates. Robert Haas

Some stylistic cleanup too, and pay attention to keeping comments in sync with code. Documentation still needs work, though I did fix the omissions in catalogs.sgml and indexam.sgml.

* Improve parser so that we can show an error cursor position for errorsTom Lane2006-03-14
| | | | | | | | | | | during parse analysis, not only errors detected in the flex/bison stages. This is per my earlier proposal. This commit includes all the basic infrastructure, but locations are only tracked and reported for errors involving column references, function calls, and operators. More could be done later but this seems like a good set to start with. I've also moved the ReportSyntaxErrorPosition logic out of psql and into libpq, which should make it available to more people --- even within psql this is an improvement because warnings weren't handled by ReportSyntaxErrorPosition.

* Reimplement the linked list data structure used throughout the backend.Neil Conway2004-05-26
| | | | | | | | | | | | | | | | In the past, we used a 'Lispy' linked list implementation: a "list" was merely a pointer to the head node of the list. The problem with that design is that it makes lappend() and length() linear time. This patch fixes that problem (and others) by maintaining a count of the list length and a pointer to the tail node along with each head node pointer. A "list" is now a pointer to a structure containing some meta-data about the list; the head and tail pointers in that structure refer to ListCell structures that maintain the actual linked list of nodes. The function names of the list API have also been changed to, I hope, be more logically consistent. By default, the old function names are still available; they will be disabled-by-default once the rest of the tree has been updated to use the new API names.

Remove all uses of strcasecmp and strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp; remove most but not all direct uses of toupper and tolower in favor of pg_toupper and pg_tolower. These functions use the same notions of case folding already developed for identifier case conversion. I left the straight locale-based folding in place for situations where we are just manipulating user data and not trying to match it to built-in strings --- for example, the SQL upper() function is still locale dependent. Perhaps this will prove not to be what's wanted, but at the moment we can initdb and pass regression tests in Turkish locale.
