A question to all pg hackers
Is anybody working on adding pipelining to set returning functions.
Not as far as I know.
How much effort would it take ?
Where should I start digging ?
I don't remember all the details, but I think the original SRF patch
that I did was pipelined rather that materialized, and there were
difficult issues that led to going with the materialized version
"first", with a pipelined version to "eventually" follow.
SFRM_Materialize is for the former and SFRM_ValuePerCall was supposed to
be for the latter. The first thread was this one:
