Exit after fatal errors in client-side compression code.
It looks like whoever wrote the astreamer (nee bbstreamer) code
thought that pg_log_error() is equivalent to elog(ERROR), but
it's not; it just prints a message. So all these places tried to
continue on after a compression or decompression error return,
with the inevitable result being garbage output and possibly
cascading error messages. We should use pg_fatal() instead.
These error conditions are probably pretty unlikely in practice,
which no doubt accounts for the lack of field complaints.
