pgsql: Fix a couple of bugs in pg_recvlogical output to stdout.

Fix a couple of bugs in pg_recvlogical output to stdout.

Don't close stdout on SIGHUP. Also, when a SIGHUP is received, close the
file immediately, rather than only after receiving some more data from
the server. Rename a variable, to avoid mentally dealing with double
negatives (not unsynced means synced).
