Hi, It seems that this commit:
commit 2cf8afe5d11377faaf5721b2c2f0089436abf704 Author: Peter Eisentraut <[email protected]> Date: Sun Oct 5 17:33:17 2008 +0000 Remove obsolete internal functions istrue, isfalse, isnottrue, isnotfalse, nullvalue, nonvalue. A long time ago, these were used to implement the SQL constructs IS TRUE, etc. removed several undocumented functions which probably weren't intended for wide use. The commit message claims these functions are "internal", though they were accessible as SQL-language functions. At least one person had been using them on 8.3, and was surprised at seeing them gone with no explanation: http://archives.postgresql.org/pgsql-novice/2010-10/msg00084.php Perhaps a mention of this change could be made in the 8.4 release notes?
