"PostgreSQL 12.3, compiled by Visual C++ build 1914, 64-bit"
I am just trying to practice LOB objects, like byteA data type, in PostgreSQL. Unfortunately, I didn't find good links regarding this so I raised the issue. Nothing else I am doing.
You should supply code that demonstrates what you have tried so far and the errors you are getting (or commented out pseudocode in the places where you are not sure what to write).
