Обсуждение: pg_dump options and perhaps 'Enhancement request'
Hi all, I don't know if I can do this stuffs. If not I would like to get it in the future. Thanks. 1-) Are there any way to do a pg_dump without '--' COMMENTS ? For example, I don't like to have this in my output file: -- -- TOC entry 19 (OID 26027) -- Name: TABLE news; Type: COMMENT; Schema: www; Owner: www -- 2-) The same for the 'blank' lines. Are there a lot of in the output file. 3-) Are there any way to get the output file with schemas in all table_names ? I would like to get this: COMMENT ON TABLE www.fo_temas IS 'xxxx.'; -- instead of: COMMENT ON TABLE fo_temas IS 'xxxx.'; Thanks in advance...

You could do this with grep (and something similar for blank lines):
pg_dump [options] dbname | grep -v "^--" > dumpfile

A simple solution for most cases: $ pg_dump [args] | egrep -v '^--|^$' >backup.sql HOWEVER, if you have the diabolical case of a table whose first column is a text type AND a row in which that first column's text begins with '--', then you'll strip those too. I think you're safe otherwise.

Ok.. ok... I know I can do a lot of things with external software or utilities (even with sed, vi or others). I can develop my ownsoftware tool to do what I want to do too. But, I think PostgreSQL team is porting this great DB to Win32 now. Ok, Ican tell you the windows guys don't have so much utilities like linux/unix guys or worse perhaps they will be users onlyand don't know how to use perl or something similar. I only want a 'clear' pg_dump if it is possible and with SCHEMA.object_name ala ORACLE if it is possible too. Thanks a lot four your answers...

This guy raises a good point, albeit indirectly. The transitions from one major version to another need to be smoother ifPostgres is going to gain any more acceptance in big database circles. A dump file shouldn't have to be messed with to reload it into the next version. There should be a 'conversion tool' or scriptbetween each version. And if a customer waits 8 versions to update, those tools, used in sequence, should be able tochange his old dump to be imported into the latest version.
