+1, the whole compress-uncompress-compress thing was why I was trying to add support to COPY to do zlib compression, which could have then been used to compress server-side and then just write the results out to a file for -Fc/-Fd style dumps. We ended up implementing the 'PROGRAM' thing for COPY, which is nice, but isn't the same. > > If SSL compression is busted on base backups, it's equally busted on > > regular connection and replication streams.

I think our answer there was always a bit of a cop out... Agreed on this also. Thanks! Stephen
