Hi everyone !
I am facing a problem after a lot of research has not found a solution. I hope some of you can enlighten me I will hold my position in 3 part: what I want, what I run, which is a problem. First of all I want to: Back up a database with all information (structure, data, functions, triggers) in a "dump" Restore the same data (structure, data, trigger, etc ...) into a new database with a different name (ex: src=foo ; dst= bar) So far not rocket science. Then what I do: pg_dump -i -F c -i -h ***.***.***.*** -p #### -U #### -f c:\dump.bak mySourceBase A creation of new base like this : CREATE DATABASE "testingBackup" WITH OWNER = postgres ENCODING = 'UTF8' TABLESPACE = pg_default LC_COLLATE = 'French_France.1252' LC_CTYPE = 'French_France.1252' CONNECTION LIMIT = -1; And finally : pg_restore -F c -h ##### -p #### -U #### -d testingBackup C:\dump.bak What problems i got pg_restore: [archiver (db)] Error while PROCESSING TOC: pg_restore: [archiver (db)] Error from TOC entry 626; 2612 16386 PROCEDURAL LANG UAGE plpgsql postgres pg_restore: [archiver (db)] could not execute query: ERREUR: language "plpgsql" already exists Command was: CREATE PROCEDURAL LANGUAGE plpgsql; WARNING: errors ignored on restore: 1 In fact there is no problem since all data is restored but in a goal of "cleanliness" I want to clean this mess and finally get no error. To this end I am open to your suggestions. Thank you in advance for your help, and I apologies for my bad English. Jean-Yves
