From 861b28f37e790e13dfae45da5042588f0ab57b1a Mon Sep 17 00:00:00 2001 From: Adrian Holovaty Date: Sat, 25 Aug 2007 18:56:43 +0000 Subject: [PATCH] Fixed #5055 -- Changed Postgres DatabaseOperations.sql_flush() to use 'SELECT setval()' instead of 'ALTER SEQUENCE', because the latter only works with Postgres 7.3+.
