IMO, he biggest differences between mysql and postgresql for beginners are:
* database authentication (pg_hba.conf and user set up)
* create/alter table syntax
* dealing with timestamps/default expressions
* update and delete statements that deal with more than one table
postgresql has a _much_ better command shell than mysql. It has
tab-completions for commands as well as database objects and has
syntax help for all commands. This is an absolutely essential help to
the beginner. (some of the gui tools, like pgadmin, have this as well
but i use the shell almost exclusively).
\h <command> in the shell will give you help for the command and
\d <table> well 'describe' the table
good luck!!
