We had never ever any reliability issues with FrontBase as long as
didn't try to insert garbage. It really doesn't like that.

As I said: depends on what you are doing.

Which version did you use where you got that terrible performance? The
latest one? There was a bug in there query planner in an old version
that totally killed some queries.

There is also the or-query problem (not sure whether that one is still
in there): if your report does something like "select bar from foo
where a = 1 or b = 1;" it didn't use indexes on a or b which is
terrible. If you have that, use separate selects combined with a union
if you can.

In my cases it was never as fast as PostgreSQL as soon as there are
more than two tables involved. But except a couple of cases where I
had to use PostgreSQL for performance reasons, I was okay with it. But
performance is not everything.

PostgreSQL is for most cases the better product, but for some cases,
FrontBase is. Depends on what you're doing how much which side has ...

PostgreSQL documentation is better, but what is your issue exactly?
The main problem I have with the FrontBase documentation is that it
mostly gives no useful examples.

As this is off-topic here: we can transfer that either to the
FrontBase list or to private mail if you like.
