To generate a sql script that will create the tables as they exist in a given database do:

pg_dump --schema-only --no-owner the_database > create_the_tables.sql

This will give you a bunch of create table statements. Just to see how portable it was I tried the above as follows:

bvm$ pg_dump -s --no-owner devdb | sqlite3 so_ans.db

And then:

bvm$ sqlite3 so_ans.db .schema
CREATE TABLE courses (
id integer NOT NULL,
name text,
created_by integer,
jc text
);

Kind of cool.

You can achieve this through phpPgAdmin just like phpMyAdmin for MySQL.

Login to phpPgAdmin select the database and then choose export.

Here's how to use pgAdmin to create a schema script that can be used with a PostgreSql database schema comparison tool such as apgdiff. These instructions are for pgAdmin3.

  1. In pgAdmin, right click on the database and click Backup.
  2. Enter an appropriate path and filename (i.e. /some/path/my_script.sql).
  3. Select Plain as the format in the format dropdown.
  4. Go to the Dump Options #1 tab and check "Only schema".
  5. Then click Backup. Then click Done.

Note: Yes, I realize that pgAdmin uses pg_dump behind the scenes to create the script, but the question was about pgAdmin, so this is the GUI method.

pgAdmin however does have a facility to do what you want:

Right-click on the database you want to export

Select Backup from the pop-up menu

Choose "format" Plain.

Choose "plain option" Only schema

At least in PgAdmin III 1.22.1 you can get CREATE script doing: 1) right-click on table name 2) "Scripts" -> "CREATE script" There are options to get SELECT, DELETE etc.
