Subject: Remove obsolete _bt_compare() comment.
X-Git-Tag: REL_13_BETA1~707
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fe9b92854e7d5f66d3abb565c5b60a879b6c9442;p=thirdparty%2Fpostgresql.git

Remove obsolete _bt_compare() comment.

btbuild() has nothing to say about how NULL values compare in nbtree.
Besides, there are _bt_compare() header comments that describe how NULL
values are handled.
