Hi Pavel,

First of all, thanks for working on this!

I'm not sure I understand the point of plugin_info in the first place,
but what would having a separate info per (plugin, function) achieve
that can't be done otherwise?

As for the current patch, I'd like to see improvements on a few things:

1) It doesn't currently compile because of extra semicolons in the
PLpgSQL_plugin struct.

2) The previous comment above the same struct still talk about the
rendezvous variable which is now gone. The comment should be
updated to reflect the new API.

3) The same comment talks about how important it is to unregister a
plugin if its _PG_fini() is ever called, but the current API does
not support unregistering. That should probably be added? I'm not
sure when _PG_fini() would be called.

4) The comment /* reserved for use by optional plugin */ seems a bit
weird in its new context.
