You have just copied the Mysql code to Postgresql. It will in no way
work. Your default for 'Date' is illegal in postgresql and hence it
must allow NULLs. There is no such thing as a 'datetime' type. There
is no such thing as 'Key'. Also your mixed case identifiers won't be
preserved. You want:
CREATE TABLE badusers (
id SERIAL PRIMARY KEY,
UserName varchar(30),
Date timestamp,
Reason varchar(200),
Admin varchar(30) DEFAULT '-'
);
CREATE INDEX UserName_Idx ON badusers(Username);
CREATE INDEX Date_Idx ON badusers(Date);
