Function: populate_geometry_columns

Schema

public

Owner

postgres

Descriptions

args: use_typmod=true - Ensures geometry columns are defined with type modifiers or have appropriate spatial constraints This ensures they will be registered correctly in geometry_columns view. By default will convert all geometry columns with no type modifier to ones with type modifiers. To get old behavior set use_typmod=false
