dumping only table definitions

Try "pg_dump -Fc" followed by pg_restore -l. You can edit the list
emitted there, then use it with pg_restore -L.

I think something involving "--tables '*.*'" might work, too.
Be careful about shell-command quoting.

I’ve tried various combinations of args to pg_dump, with -s being what I’d
like to work, but I still get all the functions.

I suppose I could filter it with Perl or Awk, but that could be tricky. In
fact, the best my searching could find is to do:

pg_dump -s databasename | awk 'RS="";/CREATE TABLE[^;]*;/'

which fails in some interesting ways.

I could dump the schema (with functions) then load it into another DB then
programmatically drop all the functions before dumping that with pg_dump,
but again why should I have to.

Is there any Pg tool that gives me just the table defs or am I going to
have to write my own?

Thanks,

Kevin

It sounds like you would best be served by installing pg_extractor. In
essence, it is a super flexible version of pg_dump. You have your choice of
exactly what you want to dump.

Thanks Melvin, that looks like it would do what I want. If it doesn’t, I’ll try Alvaro’s and Tom’s suggestions.

From my experience, this is the right solution.
