This document summarizes a presentation comparing PostgreSQL and MySQL databases. It outlines the strengths and weaknesses of each, including PostgreSQL's strong advanced features and security capabilities versus its lack of integrated replication. MySQL's strengths are its integrated replication and performance, while its weaknesses include immature security and an "closed" open source community. A variety of application types are described as better fits for each database. The document concludes with information about EnterpriseDB, a company that provides commercial support for PostgreSQL.
