I've been reading about PL/PgSQL and I find it quite powerful.
I have these question, though, which would appreciate your kind answers:
1. Can one of those script files call another such script file, so as to have some sort of an application based on them, with these files calling each other, depending on user choices, or process conditions?
2. Can PL/PgSQL files be commanded to act from an .exe program, written say using Lazarus Pascal? If so, what is basically the mechanism?
3. Also would like to ask how variables or data can be passed from PL/pgSQL to the .exe program.
