Thread: dumping data to version control using pg_dump?

dumping data to version control using pg_dump?

From
Klint Gore
Date:
Is there any way to get pg_dump to run a statement before dumping?

I'd like to do something like

pg_dump -a -c "create temp table params as select * from params where key=blah;" -d dev_db -t params -f
/svn/db/params.blah
svn commit /svn/db/params.blah

I'd rather avoid doing
psql -c "create table params_svn as select * from params where key = blah;"
pg_dump .....
psql -c "drop table params_svn"
replace tmptablename realtablename
svn commit ...

klint.

Closest you'll come is using copy...

psql -c "create temp table ...; copy from temp_table to file"

There has been some discussion about allowing COPY to work from either a
view or an arbitrary SELECT statement; check the -hackers archives.
