6.8.2 Supported PGQL Features

The In-Memory graph server (PGX) supports all PGQL features except DROP PROPERTY GRAPH.

Few features have certain limitations that are described below.

• Limitations on Quantifiers
  Although all quantifiers such as *, +, and {1,4} are supported for reachability and shortest path patterns, the only quantifier that is supported for cheapest path patterns is * (zero or more).
• Limitations on WHERE and COST Clauses in Quantified Patterns
