Обсуждение: get list of databases and tables in Postgres

LS,

Hope you can help : I am looking for equivalent sql statement for the
following in MySQL :
SHOW DATABASES

I found out that for the tables you can connect to a Postgresql specific
table information_schema.tables , but what is the corresponding table
for the names of databases under Postgresql ?

All help is highly appreciated.

Use:

select datname from pg_database;

Or simply:

\d

unless I'm missing something...

Would PGSQL respond to that as a query?

using psql
psql -l

He wants to do it through PHP - so I don't think this will work.

You could always

psql -E -l

BUT - that query *could* change depending on the version of postgresql
you're running.

TIP 5: Have you checked our extensive FAQ?

               http://www.postgresql.org/docs/faqs/FAQ.html

If you're running 7.4, look into the iformation_schema for such things.
That likely won't change.
