Not really, +1 for consistency here, and this makes the code clearer.
Different issues in the same area:
1) In vacuumdb.c, init_slot() does not check for the return value of PQsocket():
slot->sock = PQsocket(conn);
2) In isolationtester.c, try_complete_step() should do the same.
3) In pg_recvlogical.c for StreamLogicalLog() I am spotting the same problem.
I guess those ones should be fixed as well, no?
