Re: checking if sequence exists

"First, is this code in a plpgsql contex"?

 

No, that is my problem.

 

Does it have to be inside a Create function block or can just wrapping the if  with a BEGIN END; suffice ?

 

Control structures like if statements don't exist in straight sql - you need a procedural language like pl/pgsql for that. Wrapping sql statements in begin/end only affects the transactional context of the statements, it does not cause them to be interpreted as pl/pgsql. You can either create a function or you can use a "DO" block, which is sometimes what I use for deploy scripts [http://www.postgresql.org/docs/9.3/static/sql-do.html].
