Subject: [PATCH] pgsql: make wal receiver check compatible with PostgreSQL >=
 11

In PostgreSQL 11 and later the wal receiver process is named
"walreceiver" instead of "wal receiver process". This change makes the
check for a running wal receiver process compatible with both variants.

Fixes #1551
