Subject: Use logical operator && instead of & in vacuumparallel.c.
X-Git-Tag: REL_16_BETA1~1923
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=838f798f172d509f022841b82277ec84d108a379;p=thirdparty%2Fpostgresql.git

Use logical operator && instead of & in vacuumparallel.c.

As such the current usage of & won't produce incorrect results but it
would be better to use && to short-circuit the evaluation of second
condition when the same is not required.
