X-Git-Tag: REL8_5_ALPHA1~12
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a88a48011c00b6daa12e170f70b0b34cf9247113;p=postgresql

Introduce filtering dictionary support to tsearch.  Propagate --nolocale option
to CREATE DATABASE command in pg_regress to allow correct checking of
locale-sensitive contrib modules.
