35.55. transforms

`transforms`

The view transforms contains information about the transforms defined in the current database. More precisely, it contains a row for each function contained in a transform (the "from SQL" or "to SQL" function).

Column Type Description
udt_catalog `sql_identifier` Name of the database that contains the type the transform is for (always the current database)
udt_schema `sql_identifier` Name of the schema that contains the type the transform is for
udt_name `sql_identifier` Name of the type the transform is for
specific_catalog `sql_identifier` Name of the database containing the function (always the current database)
specific_schema `sql_identifier` Name of the schema containing the function
specific_name `sql_identifier` The "specific name" of the function. See routines for more information.
group_name `sql_identifier` The SQL standard allows defining transforms in "groups", and selecting a group at run time. PostgreSQL does not support this. Instead, transforms are specific to a language. As a compromise, this field contains the language the transform is for.
transform_type `character_data` `FROM SQL` or `TO SQL`
