Slightly OT: I've been using MySQL for quite some time now and whenever I start a new project thinking that I'll use Postgres this time I find myself lazily opting for something that I know and going back to MySQL. Is there a Postgres guide that is concise, easy to follow and illustrates its advantages over other relational databases. The Postgres guide[1] is too sparse currently and the beginner Apress book[2] mentioned is 644 pages long.
Probably a good idea to add a bit about serial, and sequences. This tends to confuse mysql people like myself.
I for instance don't know what happens when I copy or dump and restore a postgres table that relies on a sequence. Mysql auto-magically takes care of it by saving the next auto increment id in table dump or copy.
If you use pg_dump to dump/restore the table, it will reset the sequence to the correct value. Look at the dump file, there will be a setval of the sequence.
Agreed, especially since sequences is a more powerful tool with a wider use than auto increment. For example you can use the same sequence for multiple tables, or use them without being connected to any table.
