Subject: Suppress compiler warning in libpq_pipeline.c.
X-Git-Tag: REL_14_BETA1~402
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=522d1a89f8d7ed45681988c60bd0a687332a4023;p=thirdparty%2Fpostgresql.git

Suppress compiler warning in libpq_pipeline.c.

Some compilers seem to be concerned about the possibility that
recv_step is not any of the defined enum values.  Silence
warnings about uninitialized cmdtag in a different way than
I did in 9fb9691a8.
