Class pqxx::basic_ilostream< CHAR, TRAITS >: Access large objects directly using the blob class.
Class pqxx::basic_lostream< CHAR, TRAITS >: Access large objects directly using the blob class.
Class pqxx::basic_olostream< CHAR, TRAITS >: Access large objects directly using the blob class.
Class pqxx::binarystring: Use std::basic_string<std::byte> and std::basic_string_view<std::byte> for binary data. In C++20 or better, any contiguous_range of std::byte will do.
Member pqxx::blob::read (std::vector< std::byte, ALLOC > &buf): As libpqxx moves to C++20 as its baseline language version, this will take and return std::span<std::byte>.
Member pqxx::connection_base: Old base class for connection. They are now the same class.
Member pqxx::encrypt_password (char const user[], char const password[]): Use connection::encrypt_password instead.
Member pqxx::encrypt_password (zview user, zview password): Use connection::encrypt_password instead.
Member pqxx::from_query: Use stream_from::query() instead.
Class pqxx::from_query_t: Use stream_from::query() instead.
Member pqxx::from_table: Use stream_from::table() instead.
Class pqxx::from_table_t: Use stream_from::table() instead.
Class pqxx::largeobject: Use the blob class instead.
Class pqxx::largeobject_streambuf< CHAR, TRAITS >: Access large objects directly using the blob class.
Class pqxx::largeobjectaccess: Use the blob class instead.
Member pqxx::params::append (binarystring const &value): Append binarystring parameter.
Namespace pqxx::prepare: The new params class replaces all of this.
Member pqxx::prepare::make_dynamic_params (C &container, ACCESSOR accessor): Use params instead.
Member pqxx::prepare::make_dynamic_params (C const &container): Use params instead.
Member pqxx::prepare::make_dynamic_params (IT begin, IT end): Use params instead.
Member pqxx::row::slice (size_type sbegin, size_type send) const: I haven't heard of anyone caring about row slicing at all in at least the last 15 years. Yet it adds complexity, so unless anyone files a bug explaining why they really need this feature, I'm going to remove it. Even if they do, the feature may need an update.
Member pqxx::stream_from::stream_from (transaction_base &tx, std::string_view table, Columns const &columns): Use factory function table() or raw_table() instead.
Member pqxx::stream_from::stream_from (transaction_base &tx, from_table_t, std::string_view table, Columns const &columns): Use factory function query() instead.
Member pqxx::stream_from::stream_from (transaction_base &, std::string_view table, Iter columns_begin, Iter columns_end): Use factory function table() or raw_table() instead.
Member pqxx::stream_from::stream_from (transaction_base &, from_table_t, std::string_view table): Use factory function table() or raw_table() instead.
Member pqxx::stream_from::stream_from (transaction_base &tx, std::string_view table): Use factory function table() or raw_table() instead.
Member pqxx::stream_from::stream_from (transaction_base &, from_table_t, std::string_view table, Iter columns_begin, Iter columns_end): Use factory function table() or raw_table() instead.
Member pqxx::stream_from::stream_from (transaction_base &, from_query_t, std::string_view query): Use factory function query() instead.
Member pqxx::stream_to::stream_to (transaction_base &, std::string_view table_name, Columns const &columns): Use table() or raw_table() as a factory.
Member pqxx::stream_to::stream_to (transaction_base &tx, std::string_view table_name): Use table() or raw_table() as a factory.
Member pqxx::stream_to::stream_to (transaction_base &, std::string_view table_name, Iter columns_begin, Iter columns_end): Use table() or raw_table() as a factory.
Member pqxx::strip_t: In C++20 we'll replace this with std::remove_cvref.
