[GENERAL] select command doesnot work

[Long Cui]

HI

I installed Postgresql 8.3.3 in windows XP, try to input some commands in
windows command prompt. The create, update and insert command  work all
right, just select command.got the error message:  "more" is not internal or
external command, not runnable program or bat file. Why did I input like
"mydb => select * from .....;" but PG suppose what I enter is "more"?

thanks for help
