Alright, so, like I said, I really like this feature and would like to
see it included. To that end, I've done perhaps a bit more than a
review of the patch. Pavel, if you could go over the changes I've made
and review them and let me know if you see any problems, I'd appreciate
it. I've tried to get it ready for a committer as much as I can without
being one. :)
I moved the array iteration over into arrayfuncs.c, cleaned it up quite
a bit, cleaned up the pl/pgsql foreach function, improved the PL/PgSQL
documentation to understand FOREACH as another top-level command, added
comments all over the place, etc.
Passes all regressions too.

PL/PgSQL FOREACH cleanup
Define and rename element OID to be more consistant, ensure
that the right name gets returned in error messages, and fix
regression output to match new error message (grammar cleanup).

Improving FOREACH, code and documentation
This patch moves and reworks much of the array iteration code
that FOREACH had been implemented with to be part of arrayfuncs.c
and exported through utils/array.h. It also cleans up the error
handling and set up pieces of the FOREACH handling in pl_exec.c
Lastly, the documentation and comments are updated and improved.

Add FOREACH top-level PL/PgSQL command
This patch adds a new top-level PL/PgSQL command called FOREACH which
is intended to be for iterating over multi-value variables. This also
includes the first FOREACH type, an ARRAY iteration capability.
Patch by Pavel Stehule.
Thanks,
