This indicates that you built Postgres without compression support (no zlib).
The default for -Fc format, however, is to compress, and you get this
bleat because it can't do so. I think you can suppress the bleating by
adding "-Z 0" to the switches ... but it might be better to install zlib
and rebuild.
