My two cents: 1c) NULL is a state not a value. '' and NULL are _NOT_ the same. Hence you have SELECT blah blah... WHERE <col> IS/IS NOT NULL instead of WHERE <col> =/!= NULL.
2c) You might want to have a look at Firebird (Borland's Interbase reincarnated as Open Source) http://www.firebirdsql.org. It is a more complete RDMS than MySql, smaller and maybe easier to use than PostgreSql.
