A similar issue applies to plain SQL that's not touching any PL: In the
past, I encountered numerous situations where I'd have liked to take a
peek at the current application's queries (on MSSQL, this can be done
with SQL Profiler), but not have constant statement logging. IMHO it
would be a good idea if
- debugging could be turned on and off on-the-fly, e.g. to skip the app
startup phase. Thus I question the statement "GUC variable is sufficient"
- the mechnism would cover plain SQL too.
