write_sql

REPLACES the editor content with the given DDL after validating and formatting it; the diagram updates. If formatting or validation fails it throws and changes nothing. The editor holds the COMPLETE Postgres DDL script for the diagram, and it is always run against an empty database: an ALTER only works if the CREATE it modifies is in the same script. Extensions available: pg_trgm, btree_gin, btree_gist, vector. COMMENT ON statements appear in the diagram.
