SQL username?

[Sikora]

SQL (autom instal) is ranning with PT3, bat for import data base from PT2 I need the config. PostgreSQL settings.../ I dont now the user name/. Whot can do?

The username is postgres and the default password is dbpass if you installed postgres via the PT3 full installer.
However, if you already have postgres databases in PT2 then you'll need to know the passwords they were created with.
If you don't yet have postgres databases in PT2 then you will probably find it easiest to follow this: Tutorial: Convert PT2 non PostgreSQL database to PT3.
