PEGTL Conan package does not solve libpq as a requirement, so the user should solve postgresql by itself. Conan is a package manager and it could solve such dependency.
Now we have libpq recipe on Bincrafters' repo: https://github.com/bincrafters/conan-libpq, however it is not on Conan center yet. The option IMO is wait for Conan admin review before to integrate with PEGTL.
