Almost all languages support some kind of C bindings or provide a
dlopen-like mechanism to dynamically call C functions from shared
libraries.
RealBasic appears to have fairly dynamic, dlopen-style bindings. I'm
sure you can find more information in the manual, but here's an example
of some syntax:

You'll have to do a bit more work to produce bindings for libpq, though,
especially if you have to produce bindings for any data types (C
structures). If all you have to bind is function calls, and you can
handle any libpq-specific structures as opaque void pointers then it
shouldn't be too hard to just bind the function calls you need.
