This is another, semi independent subfeature of ECPG readahead.
It's about 150K by itself, so I send it compressed.

The purpose of this patch is to track (sub-)transactions and cursors
in ecpglib to reduce network turnaround and speed up the application
in certain cases. E.g. cursors are discarded upon ROLLBACK TO
SAVEPOINT and ecpglib needs to know about it. When an unknown
savepoint or cursor name is sent, ecpglib would not send the command
to the server in an open transaction after this patch. Instead, it flips
a "client-side error" flag and returns the same error the backend
would in this case.

Best regards,
