Subject: Make LOCK_PRINT & PROCLOCK_PRINT expand to ((void) 0) when not in use.
X-Git-Tag: REL9_4_BETA1~972
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=20803d7881c3865edede170579f55261140b5d0d;p=postgresql

Make LOCK_PRINT & PROCLOCK_PRINT expand to ((void) 0) when not in use.

This avoids warnings from more-anal-than-average compilers, and might
prevent hidden syntax problems in the future.
