I noticed that pltcl didn't have any way to get to SPI_lastoid like plpgsql does.. I started using pltcl a lot because I like to decide when and how my queries get planned.. so I put one together really quick

Sorry I don't have the original around to make a quick diff, but its a very small change... I think this should be in the next release, there's no reason not to have it.

its a function with no expected arguments, so you can use it like:
spi_exec "INSERT INTO mytable(columns...) VALUES(values..)"
set oid [spi_lastoid]
spi_exec "SELECT mytable_id from mytable WHERE oid=$oid"

It just didn't make sense for me to use plpgsql and pltcl, or just screw
them both and use SPI from C.
