pgsql: Make more consistent some translated strings related to compress

Make more consistent some translated strings related to compression

This commit changes some of the bbstreamer files and pg_dump to use the
same style as a few other places (like common/compression.c), where the
name of the compression method is not part of the string, but an
argument of it. This reduces a bit the translation work with less
string patterns.
