It should be entirely possible to run multiple connections in a single
thread as long as you manage the 'AT connName' clauses properly.
Though, IIRC, using an 'AT connName' clause on any sort of 'deallocate'
statement generates an error in ecpg:
ecpg -o test.c test.pgc
test.pgc:35: ERROR: AT option not allowed in DEALLOCATE statement
This happens when trying to deallocate a query or a prepared statement.
I don't use descriptors but the error message indicates it's _any_ sort
of deallocate.
So, it would appear that you can allocate on a connection but not
deallocate from one. :-(
I'm wonder if Tom or Michael can shine some light on this one?
Bosco.
