pg_dump in cycle

От

Dear Sirs,

I want to dump all databases, but separately each database in its own
file, not all databases in one single file as pg_dumpall does.

How can I implement that ?

Cheers,
Ilia Chipitsine

Use pg_dump instead of pg_dumpall

example:
pg_dump databaseName > databaseDumpFile

if u have many databases, you can make a script that dumps each database in
it's own file ....

U can use :
select datname from pg_database;

in order to get the list of databses

HTH

yes, but how can I integrate that query with shell script (which will
perform actual dumping) ?

I would even say, "select datname from pg_database where not
datistemplate", becuase otherwise pg_dump will complain about template0

Cheers,
Ilia Chipitsine

Check out the "psql " command.
U can use :

psql -l

which outputs sometinhg like
            List of databases
      Name       |   Owner   | Encoding
-----------------+-----------+-----------
 dragon_devel    | ptufenkji | UNICODE
 dragon_devel_v2 | ptufenkji | UNICODE
 dragon_joujou   | ptufenkji | UNICODE
 dragon_prod     | ptufenkji | UNICODE
 fgm             | gnakhle   | UNICODE
 fgm_eval        | ptufenkji | UNICODE
 hotline         | postgres  | UNICODE
 template0       | postgres  | SQL_ASCII
 template1       | postgres  | SQL_ASCII
 usj             | ptufenkji | UNICODE


for the shell script and do some text filtering in order to retrieve the
databse names.

(Or may be u can do a connection to the database from the shell script i am
not sure: i don't have a big experience in shell scripting)

This seems to be more interesting for shell scripting:

 psql -d DatabaseName -c 'select datname from pg_database where not
datistemplate' ;

     datname
-----------------
 fgm_eval
 hotline
 usj
 dragon_devel
 dragon_joujou
 dragon_devel_v2
 dragon_prod
 fgm
(8 rows)

Cheers.
Najib.
