Обсуждение: Seeking concise PL/pgSQL syntax diagram

I checked the 7.4 PL/pgSQL docs but couldn't find
a concise grammar description
e.g. a BNF diagram...is any such thing
available online ? I'm looking to possibly port a stored
procedure debugger I'm writing to support Pg.
(I'd prefer *not* to wade thru a lex/yacc definition)

TIA,

I don't think there is a grammer description in the documentation. If you
don't feel like wading through the yacc file, note that yacc can produce a
concise grammer summary as a side effect, so maybe just compiling with the
-g or -v options to yacc will produce output you can use.

Hope this helps,
