Bug reference: 15836 Logged by: Yuming Wang Email address: wgyumg@gmail.com PostgreSQL version: 12beta1 Operating system: linux Description:
Converting 'of' to a boolean type should throw an invalid input syntax. Because we said in the documentation that 'of' is not accepted as an input to the boolean data type: https://www.postgresql.org/docs/12/datatype-boolean.html ``` postgres=# select cast('of' as boolean); bool ------ f (1 row) ```
At this point raising a syntax error is undesirable, but the documentation should be modified to match the source code, which does say:
src/utils/adt/bool.c
* Try to interpret value as boolean value. Valid values are: true,
* false, yes, no, on, off, 1, 0; as well as unique prefixes thereof.
The unique prefix part needs to make it to user-facing documentation.
