Forced to select at least one extension in lql init cli

[Jovonni]

When we use lql init, we must choose at least 1 extension:

Which extensions?
Argument --extensions type [checkbox]
> Your input:
$ 
  ○ bloom
  ○ btree_gin
  ○ btree_gist
  ○ citext
  ○ hstore
  ○ intarray
  ○ pg_trgm
  ○ pgcrypto
> ◉ plpgsql
  ○ plperl

should we transfer this one to launchql-pg @pyramation?

we mentioned we can just do a default one for them, could be as simple as defaulty checking plpsql for the user
