PQXX_CHAR_STRING_ARG

#define PQXX_CHAR_STRING_ARG   typename

Template argument type for char_string.

This is a concept, so only available in C++20 or better. In pre-C++20 environments it's just an alias for typename.

PQXX_CHAR_STRINGS_ARG

#define PQXX_CHAR_STRINGS_ARG   typename

Template argument type for char_strings.

This is a concept, so only available in C++20 or better. In pre-C++20 environments it's just an alias for typename.

PQXX_RANGE_ARG

#define PQXX_RANGE_ARG   typename

Template argument type for a range.

This is a concept, so only available in C++20 or better. In pre-C++20 environments it's just an alias for typename.
