* your sql is code, and treat it as such, check it into git etc
* robust deployment strategy is essential to scaling team
* write a lot of tests
* become intimate with pg_stat_statements
* keep your transactions as short as possible while preserving safety
* avoid developers who advocate for keeping business logic out of the
database religiously (controversial)
* try to avoid assumptions that only one technical stack interacts with
your database
* do not waste time making ERDs use a tool that generates them (i like
schemaspy)
* test your DR strategy before disaster strikes
* think about security model up front
