Обсуждение: dumping only table definitions
I’m trying to figure out how to dump only the table definitions, well those and things they need directly, like sequences & types. What I do NOT want are all the millions (not literally but it feels like it J) of functions we have. Triggers would be all right if I must, as we only have a few of those.
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

Try "pg_dump -Fc" followed by pg_restore -l. You can edit the list emitted there, then use it with pg_restore -L. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services

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

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

Try "pg_dump -Fc" followed by pg_restore -l. You can edit the list
