Didn't see it there, sorry.

No, compat means compatibility towards different database systems. In this case
it more or less only means compatibility to Informix.

You can link the static library in so you're independant from the dynamic
libraries. However, I wonder if that's a good idea. ECPG's parser is build to
be in sync with the backend parser, i.e. ecpg 8.0 accepts all SQL statements
that the 8.0 backend understands which is is different set than what 8.4
understands. Also if my memory serves well, libpq has had a major version
update between 8.0 and 8.4, so if it works at all you might find that you have
to recompile the libraries too.
Is there any reason why you cannot simply recompile your programs against 8.4?
