The philosophical difference tends to be that MySQL tends to lean
towards being easier to use, and when it comes to a choice between
absolutely "correct" operation and "just do it" MySQL will just do it.
PostgreSQL tends to throw errors more often if what you're asking it
to do is not explicitly correct.
For instant, by default, this will work in mysql:
create table test (i int);
insert into test (i) values ('');
with a warning, but will produce an error in most modern versions of pgsql.
Slowly, MySQL becomes more standards compliant while pgsql gets easier
to use, but generally the differences like this remain pretty common.
