Update libpqxx to 7.3.0

7.3.0
 - `stream_to` now quotes and escapes its table name.
 - Removed `transaction_base::classname()`.  Did anyone ever use it?
 - Internal reorg of the `transaction` and `transactionfocus` hierarchies.
 - Removed the only case of virtual inheritance, related to `namedclass`.
 - Internal `concat()` for faster, simpler string concatentation.
 - Fix compile omission in string conversions for `nullptr_t`.
 - `pqxx::size_buffer()` can now size multiple values at once.
 - `multi_to_string()` to convert multiple values into one `std::string`.
 - Implicit `zview` constructor from `char const *`. (#389)
 - Many `std::string&` parameters are now `zview` or `std::string_view`.
 - Now checking statement parameter lengths for overflow.
 - `#include <array>` in connection.cxx.  (#394)
7.2.1
 - Fix infinite loop in converting `char *` to string. (#377)
 - Deprecated `namedclass`.
 - Convert an entire row using `row::as<type...>()`.
 - Internal rework of `field::to()` and `field::as()` functions.
 - Some more warning options in maintainer mode.
 - Removed the old, DocBook-based tutorial.
 - Fixed wrong `query` and SQLSTATE params to some exceptions. (#378)

Update libpqxx to 7.2.0

7.2.0
 - You can now implicitly convert a `const std::string &` to `zview`.
 - Replaced some overloads for C strings and C++ strings with `zview`.
 - Deprecating `binarystring`.  Use `std::basic_string<std::byte>` instead!
 - Array parser did not recognise escaping in unquoted values.
 - gcc10 test build fix: a result iterator is not the same thing as a `row`.
 - Doc fix: field size does _not_ include terminating zero.  (#356)
 - Fix error message in `demangle_type_name`: printed result, not raw name.
 - Fix compile warning in `demangle_type_name` on GNU systems.
 - Document that string conversions assume non-null values.
 - Start playing with C++20 _concepts._
 - Sketch out concepts-based `PQconnectdbParams` support.  (#343)
 - Add missing link to "datatypes" documentation.  (#346)
 - Supports `to_string`, `stream_to`, etc. for `binarystring`.  (#312)
 - Fixed infinite recursion when using `std::optional` in `stream_to`.  (#364)
 - Home-rolled hex-escaping.  Saves an allocation.
 - Catch floating-point negative overflow in `check_cast`, not underflow.
 - Bit more work on CMake build doc. (#318)
 - Typo in `datatypes.md`: `nullness`, not `nullness_traits`. (#353)
 - Fixed test names map in `tests/runner.cxx`. (#354)
 - Integral `from_string` now accept leading whitespace, as in composite types.
 - Experimental support basics for composite types.  (#355)
 - Use `stream_from` without knowing the number of fields.  (#357)
 - Global `size_buffer` function.
 - `quote()` now works for always-null types without conversions defined.
 - `std::nullopt` now converts to an SQL null.
 - Skip quoting and escaping array/composite fields of "safe" types.
 - New type trait: `is_unquoted_safe`.
 - Forbid invalid specialisations of `query_value`.
 - Fixed `mktemp` invocation that broke on FreeBSD.
 - Avoid unneeded encode/decode step on more binary data.
 - If `__cxa_demangle` fails, fall back on raw type name.  (#361)

Log message:
Update libpqxx to 7.1.2

Now requires c++17.

Headline:

   Easier, faster, neater: the transaction classes now have a stream
   method. You specify a query and the C++ types to which you want
   the fields converted, and you get to iterate over the rows. And
   thanks to C++14 structured bindings, you can read the fields
   straight into separate local variables:

   for (auto const [id, name]:
       tx.stream<int, std::string_view>("SELECT id, name FROM \ 
thing"))
   {
       process(id, name);
   }

   For super-fast access to a field's text-format contents, convert
   it to std::string_view. It'll give you an immediate reference
   to the buffer containing the field. Beware though: the buffer
   only holds that text for the one iteration. The next iteration
   will overwrite it.

Update libpqxx to 6.2.2

patch-ab no longer needed just since 15 Jan 2018(!)

5 years worth of changes including:
- C++11 is now required. Your compiler must have shared_ptr, noexcept, etc.
- Removed pqxx::items. Use the new C++11 initialiser syntax.
- Removed maketemporary. We weren't using it.
- Can now be built outside the source tree.
- New, simpler, lambda-friendly transactor framework.
- New, simpler, prepared statements and parameterised statements.
- Result rows can be passed around independently.
- New exec0(): perform query, expect zero rows of data.
- New exec1(): perform query, expect (and return) a single row of data.
- New exec_n(): perform query, expect exactly n rows of data.
- No longer defines Visual Studio's NOMINMAX in headers.
- Much faster configure script.
- Most configuration items are gone.
- Retired all existing capability flags.
- Documentation on readthedocs.org, thanks Tim Sheerman-Chase.
- Expose SQLSTATE error codes in sql_error exceptions.
- Adds a first-generation parser for SQL arrays.
