​It isn't "plsql", just "SQL" - but I might be losing something in the
translation. "pl/sql" is an Oracle thing that is indeed like "pl/pgsql" -
but "pl/sql" does not directly work, let alone well, on PostgreSQL...

Anyway, writing a function in "LANGUAGE sql" means you are limited to only
those things SQL can do. Using pl/pgsql gives you access to the power of
procedural logic among other things.

There is no "better" - but the general rule is if it can be done using SQL
then do so since you are likely to see better performance. When you need
to do something SQL cannot do then consider pl/pgsql.
