Cursors are not supported in PL/pgSQL.  I don't see a TODO item to fix
this.

Fixing the syntax to support cursors is easy.  The problem then is
that PL/pgSQL uses SPI, and SPI does not support cursors.  In spi.c
there is a bit of code for cursor support, with the comment
	/* Don't work currently */

Is adding cursor support to SPI a bad idea?  Is adding cursor support
to PL/pgSQL undesirable?

Can anybody sketch the problems which would arise when adding cursor
support to SPI?

Thanks.
