- pg_fatal("cannot restore from compressed archive (compression not
supported in this installation)");
+ pg_fatal("cannot restore data from compressed archive (compression not
supported in this installation)");
Hmm. I don't mind changing this part as you suggest.
-#ifndef HAVE_LIBZ
- if (AH->compression_spec.algorithm == PG_COMPRESSION_GZIP)
- pg_fatal("archive is compressed, but this installation does not
support compression");
-#endif
However I think that we'd better keep the warning, as it can offer a
hint when using pg_restore -l not built with compression support if
looking at a dump that has been compressed.
