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).
Table 36.51. transforms Columns
| Name | Data 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 Section 36.40 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
