Detailed Description

You cannot convert an unsigned char to/from SQL.

Converting this type may seem simple enough, but it's ambiguous: Did you mean the char value as a small integer? Or were you thinking of a single-character string (and if so, using what encoding)? Or perhaps it's just a raw byte value?

If you meant it as an integer, use an appropriate integral type such as int or short or unsigned int etc.

If you wanted a single-character string, use std::string_view (or a similar type such as std::string).

Or if you had a raw byte in mind, try pqxx::bytes_view instead.
