Subject: Release XactLockTable share lock immediately after this lock is acquired
X-Git-Url: http://waps.l3s.uni-hannover.de/gitweb/?a=commitdiff_plain;h=3ac8dd7a6ca0edc4fd13372ae574d645ccb709f6;p=users%2Fbernd%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.
