Hi,

So nobody can help me to write the SELECT that will return the SEQUENCE names, and their linked columns and their linked tables ?
Are the system tables documented somewhere ?

 
Cheers,

Yes, but when I change a database schema and I reload the data, and I need to resynch the SEQUENCE so that the INSERT command will work !

 
Have fun,

I never bother resetting sequences. It's not like the numbers mean
anything...

Have a nice day,

Of course -- in the "internals" section.  You need pg_class where
relkind = 's', pg_depend, and possibly pg_attribute.
