Heikki Linnakangas	283939a321	varstr_cmp and any comparison function that piggybacks on it can return any negative or positive number, not just -1 or 1. Fix comment on varstr_cmp and citext test case accordingly. As pointed out by Zdenek Kotala, and buildfarm member gothic moth.	17 years ago
Tom Lane	13fdd0e4d1	Add some more citext test cases, per David Wheeler. Also remove the citext-to-and-from-xml tests, since those caused variation between installations with or without libxml without really proving much. Instead repurpose citext_1.out as the expected results in glibc en_US (and probably other) locales.	17 years ago
Tom Lane	5bc561a16a	Add some additional casts and regression tests for the citext data type. David Wheeler	18 years ago
Tom Lane	c8572986ad	Allow I/O conversion casts to be applied to or from any type that is a member of the STRING type category, thereby opening up the mechanism for user-defined types. This is mainly for the benefit of citext, though; there aren't likely to be a lot of types that are all general-purpose character strings. Per discussion with David Wheeler.	18 years ago
Tom Lane	ab9907f5e5	Add a new, improved version of citext as a contrib module. David E. Wheeler	18 years ago
