(Prompted by a puzzled user on IRC)
Ten years ago, nearly, we made this commit
<https://github.com/postgres/postgres/commit/8a2cdd77ad5c0a4f8902ea86d0377336e076abcb>
(see what a good thing it is we carefully got all the history
transferred to git?)
The comment on the commit says:
EXECUTE of a SELECT ... INTO now draws a 'not implemented' error, rather than executing the INTO clause with
non-plpgsqlsemantics as it was doing for the last few weeks/months. This keeps our options open for making it do
theright plpgsql-ish thing in future without creating a backwards compatibility problem. There is no loss of
functionalitysince people can get the same behavior with CREATE TABLE AS.
Do we really still need to keep out options open on this after all that
time?
cheers
