Subject: nbtree: consistently use minoff variable.
X-Git-Tag: REL_18_BETA1~1467
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=18ea6b3d0da357b5874ab9cf41350d4473b01ee9;p=postgresql.git

nbtree: consistently use minoff variable.

This was arguably an oversight in commit 29b64d1de7, which moved this
code from nbtutils.c to its nbtsearch.c caller.
