Try it with plain pg_dump.

pg_restore -h localhost -p 5532 dump.sql

I tried this, but nothing appears to happen when entering the commands. Attached is a screenshot of the shell window - what am I doing wrong?

those are system shell commands, not psql sql commands. catch-22, in the windows environment, postgresql's command tools probably aren't in the path, so to execute the above commands try this...

start -> run -> CMD <enter>

(or, click on an 'Command Prompt' shortcut).

C:\Users\YourName> path "c:\Program Files\PostgreSQL\9.4\bin";%path%
C:\Users\YourName> pg_dump -Fc -p 5432 <dbname> | pg_restore -p 5532

Thanks. When I do this I get an error: could not find a "pg_dump" to execute - I've used the path "C:\Program Files\PostgreSQL\9.3\bin";%path% which appears to be correct

Sorry, forgot to add: once I get the warning that the Pg_dump can't be found there is then a password prompt; I tried the db password and the pc password but both fail:

Password:
pg_dump: [archiver (db)] connection to database "irll_project" failed: FATAL: p
assword authentication failed for user "killian"

Do you have a user killian in the database? If not you can either create it or use pg_dump with the –U switch to set it to the existing user (and with privileges on the database of course).

pg_restore: [archiver] input file is too short (read 0, expected 5)

if your postgres is installed somewhere else, replace "c:\Program Files\PostgreSQL\9.4\bin" in the PATH command with its actual location \bin ....
