I will check that this weekend. Thanks.
Does this buildfarm member need to run continuously?

I just did a quick check of my changes and the changes seem minor. The
only major changes are the port specific parts in src/backend/port.
Postgresql is running. I can login with psql and create a table, insert
data and query it. ODBC access is also working. There does seem to be a
problem with starting autovacuum, which I am still investigating.

I will try to check on that this weekend.
I also found (I think) two places where the implementation of a
function contained slightly different parameters from the declaration
which breaks on Haiku as an int is not the same as int32 (see src/
backend/catalog/dependency.c function deleteOneObject for one of
those).
