==PostgreSQL - MySQL Compare==
#MySQL began development with a focus on speed while PostgreSQL began development with a focus on features and standards. Thus, MySQL was often regarded as the faster of the two.[http://www.wikivs.com/wiki/MySQL_vs_PostgreSQL#Beginnings]
# Both PostgreSQL and MySQL support Not-Null, Unique, Primary Key and Foreign Key constraints. However MySQL silently ignores the CHECK constraint
#MySQL supports stored procedures, per se; PostgreSQL supports stored functions, which are in practice very similar.
