Hi !
At present, I am using MySQL as backend for my work.
Because of the licensing implications, I am considering to shift from MySQL to pgsql.
Typically, my apps are multi-user, web based or LAN based.
1) Read over the internet that ---
Postgres is not threaded, but every connection gets it's own process. The OS will distribute the processes across the processors. Basically a single connection will not be any faster with SMP, but multiple connections will be.
MySQL is multi-threaded server so it can use many processors. A separate thread is created for each connection.

2) I run MySQL from a USB stick.
There is no installation required (on WinXP.). (not tried on Ubuntu)
Is it the same for pgsql?
3) Can I simulate MySQL's TINYINT data-type (using maybe the custom data type or something else)
Thanks,
Vineet
