error C2039: 'converts_from_string': is not a member of 'pqxx::string_traits<pgvector::Vector>' about libpqxx

There should be libpqxx version requirement for pgvector-cpp to work, you should open this issue in pgvector-cpp repository.

There should be libpqxx version requirement for pgvector-cpp to work, you should open this issue in libdx repository.

I'm unable to find libdx repository. Can you provide the link for this repository?

Resolved: pgvector/pgvector-cpp#3

@VamshiGowdaHP it sounds like the authors of pgvector-cpp have built libpqxx support, but haven't updated it to the latest libpqxx versions. The newer versions add a few requirements for how to define conversion support between a C++ type and its SQL text equivalent. in particular, the conversion now needs to define converts_to_string and converts_from_string. (See include/pqxx/doc/datatypes.md for the current requirements.)

I suppose we can close this ticket now?

[vamgowda-git]

Yes, you can close this ticket.
