It doesn't help, but there are many other differences that are as big or
bigger.  Here are a few samples off the top of my head:

1) Performance issues due to MVCC (MySQL fans love to point out how
fast they can do select count(*) from x)
2) Not knowing you have to run vacuum analyze and therefore never seeing a
good query result
3) Unfair comparison of PostgreSQL with robust WAL vs. MySQL+MyISAM on
write-heavy worksloads

These are real issues, which of course stack on top of things like
outdated opinions from older PG releases with performance issues resolved
in the last few years.
