PostGraphile supports a wide range of PostgreSQL functions; however we do not support:

• VARIADIC functions
• overloaded functions (because it's not currently possible to expose them neatly over GraphQL)

• functions that return record without any more type information (because we don't know what columns that record will contain, and thus cannot convert it to GraphQL)

  • to solve this, change record to be the name of a composite type that you've defined with CREATE TYPE (or similar)

Thanks

This page used to be a lot larger; until community contributor Matt Bretl swooped in and lifted almost all the restrictions — thanks Matt!
