Yes, I was thinking of doing a pg_dumpall, but my only worry was that the singl file is going to be pretty large. I guess I don't have to worry too much about that.   But my question to you sir is, If I want to create the development db using this pg dump file, how do I actually edit create tablespace statements so they will be created in the directory I want them to be. Or should I even worry about this.. (I want my data directory to be in E: drive including all the tablespaces.)   Thank you very much for your reply.

A standard pg_dumpall --globals will dump the create tablespace statement, which you can edit as needed for your new machine. A plain pg_dump of the database will dump out the tables with tablespace statements. A pg_dumpall of the whole database cluster can also be used to do this.
