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.
