RE: AW: [HACKERS] Begin statement again

We, that is ecpg, will need BEGIN and END to include blocks of Pl/pgSQL.
I think this can be modelled after ORACLE's PL/SQL. in your embedded SQL
code you say:

	...
	exec sql begin;
		<some PL/SQL code, for instance the call of a stored
procedure>
	exec sql end;
	...

And I'd really like to call a stored procedure from my C program.
