Peter Eisentraut	414c5a2ea6	Per-column collation support This adds collation support for columns and domains, a COLLATE clause to override it per expression, and B-tree index support. Peter Eisentraut reviewed by Pavel Stehule, Itagaki Takahiro, Robert Haas, Noah Misch	15 years ago
Tom Lane	304845075c	Use array_contains_nulls instead of ARR_HASNULL on user-supplied arrays. This applies the fix for bug #5784 to remaining places where we wish to reject nulls in user-supplied arrays. In all these places, there's no reason not to allow a null bitmap to be present, so long as none of the current elements are actually null. I did not change some other places where we are looking at system catalog entries or aggregate transition values, as the presence of a null bitmap in such an array would be suspicious.	15 years ago

Tom Lane	29d2f86a31	Allow zero-dimensional (ie, empty) arrays in contrib/ltree operations. The main motivation for changing this is bug #4921, in which it's pointed out that it's no longer safe to apply ltree operations to the result of ARRAY(SELECT ...) if the sub-select might return no rows. Before 8.3, the ARRAY() construct would return NULL, which might or might not be helpful but at least it wouldn't result in an error. Now it returns an empty array which results in a failure for no good reason, since the ltree operations are all perfectly capable of dealing with zero-element arrays. As far as I can find, these ltree functions are the only places where zero array dimensionality is rejected unnecessarily. Back-patch to 8.3 to prevent behavioral regression of queries that worked in older releases.	16 years ago

Teodor Sigaev	8eee65c996	ltree support for multibyte encodings. Patch was made by laser <laserlist@pgsqldb.com> with some editorization by me.	18 years ago
Alvaro Herrera	f8c4d7db60	Restructure some header files a bit, in particular heapam.h, by removing some unnecessary #include lines in it. Also, move some tuple routine prototypes and macros to htup.h, which allows removal of heapam.h inclusion from some .c files. For this to work, a new header file access/sysattr.h needed to be created, initially containing attribute numbers of system columns, for pg_dump usage. While at it, make contrib ltree, intarray and hstore header files more consistent with our header style.	18 years ago

Bruce Momjian	f3d99d160d	Add CVS tag lines to files that were lacking them.	20 years ago
Neil Conway	8e5a10d46c	This patch makes the error message strings throughout the backend more compliant with the error message style guide. In particular, errdetail should begin with a capital letter and end with a period, whereas errmsg should not. I also fixed a few related issues in passing, such as fixing the repeated misspelling of "lexeme" in contrib/tsearch2 (per Tom's suggestion).	20 years ago
Tom Lane	25c00833cb	Add defenses against nulls-in-arrays to contrib/ltree. Possibly it'd be useful to actually do something with nulls, rather than reject them, but I'll just close the hole for now.	20 years ago
Bruce Momjian	1dc3498251	Standard pgindent run for 8.1.	20 years ago
Tom Lane	0bd61548ab	Solve the 'Turkish problem' with undesirable locale behavior for case 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.	22 years ago
