Thread: how to emit line number in a function?
I couldn't find any useful references in the docs or archives for emitting the line number of a plpgsql function (in a RAISE statement). I'd like to use it for debugging some complex functions. Does anyone have any tips on where to look, or an example of this?

However, recent versions of PG should display the line number of a RAISE NOTICE or similar if you have the error verbosity high enough. -- Richard Huxton Archonet Ltd

Is there any other way to get the current line number, for example, an inline function call to elog(?) or something? It's not a huge deal, but it would be useful for debugging and timings. -- _______________________________ This e-mail may be privileged and/or confidential, and the sender does not waive any related rights and obligations.

Have a look at the m4 macro processor
changequote({,})dnl
define({func_body},{$$begin
raise exception 'I barfed on line #__line__';
end$$})dnl
create function some_func()
returns whatever
as func_body
language plpgsql;
This can be useful sometimes... but may ADD to your debugging
headaches if not used artfully!
