Fix latent bug in ExecSeqRestrPos: it leaves the plan node's result slot
Tom Lane <tgl@sss.pgh.pa.us>
Fix latent bug in ExecSeqRestrPos: it leaves the plan node's result slot in an inconsistent state. (This is only latent because in reality ExecSeqRestrPos is dead code at the moment ... but someday maybe it won't be.) Add some comments about what the API for plan node mark/restore actually is, because it's not immediately obvious.
