When debugging programs, I need to frequently drop a database of Postgresql, and then re-create it again.

To convenient, I want to execute this in a single command line like following:

psql -c "DROP DATABASE my_db; CREATE DATABASE my_db;"

But I get a error:

ERROR: DROP DATABASE cannot run inside a transaction block

Is there a way I can do it? Thanks!

You can use the -c option repeatedly:

psql -c 'DROP DATABASE my_db' -c 'CREATE DATABASE my_db'
