Simplest way I know of is to write a C function which fires off a
shell script which in turn executes psql with appropriate parameters.
The C function can pass it individual variables, or the entire SQL
string.
The reason for the shell script is that way the database, port, etc.
are easy to change and don't require a re-compile / reload.
One thing you definately cannot do is a C function which creates a new
database connection on it's own. Doesn't like that at all!
I've implemented a form of 'su' for postgres doing that -- makes a
second connection back into the database. A middle man shell script
ensures that only a few specific requests can be made (one is actually
creating a system user with very specific parameters).
