Description
in postgresql `string_agg` allows you to have a nullable column as the first arg expression so should the following instance also exist?
```haskell
-- Database/Beam/Postgres/Syntax.hs
instance IsSqlExpressionSyntaxStringType PgExpressionSyntax a =>
IsSqlExpressionSyntaxStringType PgExpressionSyntax (Maybe a)
```
