Hello PostgreSQL Community, I have 25+ years of experience with some other RDBMS, but I am a PostgreSQL starter, so I assume the following is rather a simple beginner's question...:
I like to store just a single bit but that can be either 1 or 0, so I tried to do this: CREATE TABLE T (c BIT); INSERT INTO T VALUES (1); -- I MUST NOT change both lines in any way as these are part of a third-party application! Unfortunately this tells me: column "c" is of type bit but expression is of type integer So I logged in as a cluster admin and I tried this: CREATE CAST (integer AS bit) WITH INOUT AS IMPLICIT; Unfortunately that tells me: cast from type integer to type bit already exists This is confusing! Apparently PostgreSQL 15.3 comes with the needed cast out-of-the-box but it does not apply it? This is confusing! What is my fault? Thanks! -Markus
