I might have missed the discussion, but I'd love to see a more flexible
interface for configuration parameters. For instance, it'd be great if
we can specify which procedural languages to track in the `pl' GUC.
Moreover, if it'd be possible to specify which specific functions we
want to try, then that would be awesome as well.
For instance, possible configuration combinations for track_functions
`pl:*' - Tracks procedural, SQL and C (not internal)
functions in the `public' schema.
`pl:pgsql' - Tracks only PL/pgSQL functions.
`pl:scheme' - Tracks only PL/scheme functions.
`foo(int, int)' - Tracks related `foo' function in the public
`stock.foo(int, int)' - Tracks related `foo' function in the `stock'
`pl:stock.*' - Tracks procedural, SQL and C (not internal)
functions in the `stock' schema.
Syntax can obviously be much more consistent. (These are just what I
come up with for the very moment.) And I'm aware of the overhead and
complexity(?) this sort of scheme will bring, but I really want to use
such a useful feature with mentioned flexibilities.
