There's also an error in the document (which is not surprising, since
the MySQL documentation on spatial is a little misleading, with most
all of the OGC functions documented when only the constructors and
accessors are actually fully implemented) which indicates that MySQL
supports:
Buffer(g,d)
ConvexHull(g)
Difference(g1,g2)
Intersection(g1,g2)
SymDifference(g1,g2)
Union(g1,g2)
When it actually does not.

This seems to cover most of the major issues, although I'd point
out that the speed difference between the two is mostly obvious
when running single (or only a few) connections to the database; if
you need something that can support dozens / scores (or more) of
simultaneous connections the speed difference is markedly less, and
sometimes is reversed with Postgres showing an advantage.

Last year I was ask by my manager to compare the spatial capabilities
of Postgres and mysql.
See attached the report I gave him... it was a 1 hour job. so no
guarantees
