Hello all,
I'm trying to write a postgres client application in C.
I'm having to make use of some existing in-house code that soley uses ECPG to
interact with a number of databases. However, I need to exploit some
lower-level libpq functionality directly.
Does anyone know how I can get hold of
Does anyone know if the Postgres DBD for the Perl DBI supports the array
datatype?
Thanks in Advance !

I use numeric array columns with DBD::Pg. What do you define as "support"?

What if I want to do this on the server side (because it's much, much
faster)? Does COPY use the default encoding of the database? If not,
what?

Sorry, sloppy use of terminology. I should have said "UTF signatures"
aka the "byte order mark". IOW, the "magic number" bytes commonly found
at the front of UTF encoded files:

That page is too generic; what would be helpful is a section in the doc for
each command that is affected by I18N/L10N considerations, that identifies how
that specific command behaves.

You would need to write that in C.

Check out Power Architect. Pre-major release, it has some bugs, but
generally works well. It can also forward and reverse engineer.
