Thanks for the help. After a quick intro to sed (I'm a Windows user) I have this working a treat for me. I used the following slight mod and it seems to handle both sql and pl/pgsql on 8.1.4On Thu, Nov 02, 2006 at 09:57:28AM -0500, Oisin Glynn wrote:I have named all my functions in a pretty unique way and would like to export just my functions. Is there any way to move just these functions from one db to another.has anyone got a clever piece of SQL that spits out ddl from a select on pg_proc? Or could I use the copy command on pg_proc to spit my functions to file and then copy them into the new db? My issue is that I have allot of dblink and other things I do not want or need in the db and do not want to propagate this any further.I would say the easiest is to use pg_dump and then filter the output. It's simple enough for sed I think: pg_dump database | sed -ne '/^CREATE FUNCTION tag/,/^--/p' works well here... Replace tag with a pattern matching your functions. If you're using pl/pgsql you may need to do something more clever with the end marker... Have a nice day,
pg_dump database | sed -ne '/^CREATE FUNCTION tag/,/^-- TOC entry/p'The "-- TOC entry" seems to act as a perfect end tag. I actually dumped the db as plain from pgAdmin and used this file as input to sed rather than piping the pg_dump into sed. The only difference was that I needed double quotes not single quotes in my sed command so command ended up like
sed -ne "/^CREATE FUNCTION tag/,/^-- TOC entry/p" mybackupfile.backup >myfunctions.sql
Thanks, Oisin
