Postgresql: how to create table only if it does not already exist?

Question

In Postgresql, how can I do a condition to create a table only if it does not already exist?

Code example appreciated.

Answer 1

Just create the table and don't worry about whether it exists. If it doesn't exist it will be created; if it does exist the table won't be modified. You can always check the return value of your SQL query to see whether the table existed or not when you executed the create statement.
