Thread: pg_dump -- data and schema only?
I haven't seen this option, and does anyone thing it is a good idea? A option to pg_dump and maybe pg_dump all, that dumps only the table declarations and the data. No owners, tablespace, nothing. This, I think, would allow more generic PostgreSQL data transfers.

pg_dump -s maybe?
See man pg_dump:
-s
--schema-only Dump only the object definitions (schema), not data.
Usually one dumps the database with -Fc and then construct
SQL for data and DDL via pg_restore from this binary dump.
You can then use pg_restore -l, edit (for example via sed)
and use it with -L to only generate SQL for these objects.

When you dump the schema, it includes all the tablespaces, namespaces, owners, etc. Just the table nd object declarations and data would be useful.

Reread my comment on the -l / -L option to pg_restore. You can do all that with it :-) -- Tino Wildenhain <tino@wildenhain.de>

pg_dump -t table ?

I guess what I'm not being very clear. pg_dump -# mydb >> -- -- PostgreSQL database dump -- SET client_encoding = 'SQL_ASCII'; SET check_function_bodies = false; SET client_min_messages = warning; SET default_with_oids = true; -- -- Name: rtz; Type: TABLE; Schema: public; Owner: markw; Tablespace: -- CREATE TABLE rtz ( tlid integer, rtsq integer, zip4l integer, zip4r integer ); -- -- Data for Name: rtz; Type: TABLE DATA; Schema: public; Owner: markw -- COPY rtz (tlid, rtsq, zip4l, zip4r) FROM stdin; 208014102 0 0 0 208014098 0 0 0 207023736 0 0 0 208014112 0 0 0 207027749 0 0 0 ..... That way, it can go "easily" between various PG versions.
