hi there, trouble means: it doesn't show ver_id_seq, nor own_id_seq when doing a \ds but it brings up an error "cannot create sequence) if i want to create table ver (id serial, ...); this happend after i mistakenly did create table cng (id serial, ver_id int4 constraint ver_id_cst reference ver (id)); without having create table ver (id serial, ...); this happend twice. the cli and ver now are nono's for my database. thanks for help olaf Peter Eisentraut schrieb: > > Olaf Marc Zanger writes: > > > as it seems postgresql 7.0 has trouble to create > > > > ver_id_seq > > Define "trouble". > > -- > Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/ -- soli-con Engineering Zanger Dipl.-Ing.

What is the *exact* text of the error message? (That ain't it.)
I am guessing that a Unix file matching the desired sequence name got
left around in your database directory, and that removing this file
would allow you to create the sequence. However, I can't duplicate
any such problem by following the procedure you describe in 7.0.2...

Yes, if there's not any corresponding system-catalog entry for them.
