Message-ID: <18222-de86a89e6ed68f3d@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18222
Logged by: Jinsheng Ba
Email address: bajinsheng@u.nus.edu
PostgreSQL version: 16.1
Operating system: Ubuntu
Description:
SELECT ('1'-to_hex(2))::BOOLEAN; -- ERROR: cannot delete from scalar
This error looks strange to me as I do not understand what this error
means.
If I execute the following query, there is no error instead:
SELECT '1'-2; -- {-2}
