Subject: Release XactLockTable share lock immediately after this lock is acquired
X-Git-Tag: REL6_5~118
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=219bb76d61b3beee1e93295cf9cc4725da64a6c9;p=users%2Fhanada%2Fpostgres.git

Release XactLockTable share lock immediately after this lock is acquired
(no sense to hold it) or we'll be out of lock entries.
Great thanks to Hiroshi Inoue.
