In pgAdmin III you can:

• right-click a table;
• scripts;
• CREATE script;
• save the script from the SQL Editor.

If one has to do this for more than one table, is there a way to combine the scripts in one file (apart from manually copy-pasting them)? If this can be done via psql prompt or phppgadmin, that will be ok too.

Here's a way using pgAdmin.

• Right-click on your database (or schema).
• Choose "backup"
• Under "Format" choose "plain"
• Under "Dump Options #1" choose "Only schema"
• Under "Objects" choose the tables you want.

Then click "backup". The output should be a plain text file with the create table statements.

Here's the PgAdmin documentation on backup.
