There's a GUI debugger from EnterpriseDB I believe, but I've no idea how good it is. Any users/company bods care to let us know?
It's an excellent debugger (of course, I'm a bit biased).
We are working on open-sourcing it now - we needed some of the plugin features in 8.2.
As Jonah pointed out, we also have a PL/pgSQL profiler (already open-sourced but a bit tricky to build). The profiler tells you how much CPU time you spent at each line of PL/pgSQL code, how many times you executed each line of code, and how much I/O was caused by each line (number of scans, blocks fetched, blocks hit, tuples returned, tuples fetched, tuples inserted, tuples updated, tuples deleted).
It's been a while since I looked at it, but I seem to remember that it spits out an XML report that you can coax into a nice HTML page via the XSLT.
The plugin_profiler needs to be converted over to the plugin architecture in 8.2, but that's not a lot of work.
