Tips for People Moving to Postgres

Ryan Booz shares a few bits of advice about people learning about Postgres:

I was much further in my SQL Server career than I should have been before I understood the usefulness of APPLY in T-SQL. I didn’t realize that APPLY isn’t a SQL standard and so when I started using PostgreSQL and needed similar functionality, I was perplexed trying to find the equivalent. Fortunately, I wasn’t the only one searching.

My recollection here is that Microsoft introduced the APPLY operator before there was an ANSI standard, so as long as my memory isn’t faulty here, this wasn’t a case of a vendor just deciding to name something differently for the sake of it.

Regardless, Ryan has a lot of good advice for learners of PL/SQL.
