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

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.
