SQL is about 3-5 languages which share some syntax DDL,DML,DQL,cursor
manipulation,...

And we do currently have seek/read/write for LOs, possibly as a relict
from postquel.

We also have PL/PGSQL and other PL's that can be used from wihin SQL, so
for me the
borders between different languages seem quite blurred.

What I hoped the standard would have is something like cursor ops on a
field in on
outer cursors current record.
