Subject: Fix oversight: there's no reason for PG_TRY to use sigsetjmp(buf,1)
X-Git-Tag: REL8_0_0BETA3~61
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9f6df6c4a6b76be47be645a4041f93eac87c3c95;p=postgresql

Fix oversight: there's no reason for PG_TRY to use sigsetjmp(buf,1)
since we don't change the signal mask during normal backend operations.
Use sigsetjmp(buf,0) to avoid many unnecessary kernel calls.
