* Remove hardcoded hash opclass function signature exceptionsPeter Eisentraut2024-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | hashvalidate(), which validates the signatures of support functions for the hash AM, contained several hardcoded exceptions. For example, hash/date_ops support function 1 was hashint4(), which would ordinarily fail validation because the function argument is int4, not date. But this works internally because int4 and date are of the same size. There are several more exceptions like this that happen to work and were allowed historically but would now fail the function signature validation. This patch removes those exceptions by providing new support functions that have the proper declared signatures. They internally share most of the code with the "wrong" functions they replace, so the behavior is still the same. With the exceptions gone, hashvalidate() is now simplified and relies fully on check_amproc_signature(). hashvarlena() and hashvarlenaextended() are kept in pg_proc.dat because some extensions currently use them to build hash functions for their own types, and we need to keep exposing these functions as "LANGUAGE internal" functions for that to continue to work.

* Doc: modernize comment for boolin().Tom Lane2023-10-19
| | | | | | | | | | Most of the behavior described by this comment was moved to parse_bool_with_len() some time ago. Move what's still valuable there too, and drop the rest. Peter Smith Discussion: https://postgr.es/m/CAHut+PtMJURKp=U8Z=Ktp0zV40sEb1f-iEk9FvY2GQe+5ZBnwg@mail.gmail.com

* Convert a few datatype input functions to use "soft" error reporting.Tom Lane2022-12-09
| | | | | | | | | | | | | | | This patch converts the input functions for bool, int2, int4, int8, float4, float8, numeric, and contrib/cube to the new soft-error style. array_in and record_in are also converted. There's lots more to do, but this is enough to provide proof-of-concept that the soft-error API is usable, as well as reference examples for how to convert input functions. This patch is mostly by me, but it owes very substantial debt to earlier work by Nikita Glukhov, Andrew Dunstan, and Amul Sul. Thanks to Andres Freund for review.

* Clean up some code using "(expr) ? true : false"Michael Paquier2021-09-08
| | | | | | | | | | All the code paths simplified here were already using a boolean or used an expression that led to zero or one, making the extra bits unnecessary.

* Simplify and standardize conversions between TEXT datums and ordinary CTom Lane2008-03-25
| | | | | | | | | | | | | | | | | | | | strings. This patch introduces four support functions cstring_to_text, cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and two macros CStringGetTextDatum and TextDatumGetCString. A number of existing macros that provided variants on these themes were removed. Most of the places that need to make such conversions now require just one function or macro call, in place of the multiple notational layers that used to be needed. There are no longer any direct calls of textout or textin, and we got most of the places that were using handmade conversions via memcpy (there may be a few still lurking, though). This commit doesn't make any serious effort to eliminate transient memory leaks caused by detoasting toasted text objects before they reach text_to_cstring. We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few places where it was easy, but much more could be done. Brendan Jurd and Tom Lane

* Downgrade implicit casts to text to be assignment-only, except for the onesTom Lane2007-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | from the other string-category types; this eliminates a lot of surprising interpretations that the parser could formerly make when there was no directly applicable operator. Create a general mechanism that supports casts to and from the standard string types (text,varchar,bpchar) for *every* datatype, by invoking the datatype's I/O functions. These new casts are assignment-only in the to-string direction, explicit-only in the other, and therefore should create no surprising behavior. Remove a bunch of thereby-obsoleted datatype-specific casting functions. The "general mechanism" is a new expression node type CoerceViaIO that can actually convert between *any* two datatypes if their external text representations are compatible. This is more general than needed for the immediate feature, but might be useful in plpgsql or other places in future. This commit does nothing about the issue that applying the concatenation operator || to non-text types will now fail, often with strange error messages due to misinterpreting the operator as array concatenation. Since it often (not always) worked before, we should either make it succeed or at least give a more user-friendly error; but details are still under debate. Peter Eisentraut and Tom Lane

* The added aggregates are:Bruce Momjian2004-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | (1) boolean-and and boolean-or aggregates named bool_and and bool_or. they (SHOULD;-) correspond to standard sql every and some/any aggregates. they do not have the right name as there is a problem with the standard and the parser for some/any. Tom also think that the standard name is misleading because NULL are ignored. Also add 'every' aggregate. (2) bitwise integer aggregates named bit_and and bit_or for int2, int4, int8 and bit types. They are not standard, but I find them useful. I needed them once. The patches adds: - 2 new very short strict functions for boolean aggregates in src/backed/utils/adt/bool.c, src/include/utils/builtins.h and src/include/catalog/pg_proc.h - the new aggregates declared in src/include/catalog/pg_proc.h and src/include/catalog/pg_aggregate.h - some documentation and validation about these new aggregates.

* Solve the 'Turkish problem' with undesirable locale behavior for caseTom Lane2004-05-07
| | | | | | | | | | | | | conversion of basic ASCII letters. 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.
