How to create enums using pgAdmin?
Creating ENUM using pgadmin:
Schema -> Create... -> Type... -> Definition -> Type = Enumeration
Changing column type to enum using SQL:
ALTER TABLE <table> ALTER column TYPE <new_type> USING <column>::<new_type>
For pgAdmin 1.22 and above, the path is
File > Options > Display_Database_objects
scroll down to the bottom
Check or uncheck "Type"
I fired up a copy of pgadmin and noticed what you said, I couldn't see my 'types'. If you pull down the main menu and go to preferences, then scroll down until you see Type, then check the box and refresh you screen, then types become visible.
Just Create "type" in types option which is located in the schema section.While creating type just select enumeration type and fill your value in label
