This bumps the libpq client-side PostgreSQL library minimum required
version from 9.1 to 10.0.
- Sanity check: PQlibVersion -> PQencryptPasswordConn (available since
libpq 10.0)
- PQsetErrorContextVisibility (available since libpq 9.6)
- lo_truncate64 (available since libpq 9.3), if 32-bit system doesn't
support lo_*64 functions, error is returned and functions are always
available
Additionally, the conditional functions usages in pdo_pgsql and pgsql
extensions that got piled up are cleaned and synced:
- pg_prepare (PQprepare available since libpq 7.4)
- pg_query_params (PQexecParams available since libpq 7.4)
- pg_result_error_field (PQresultErrorField available since libpq 7.4)
- pg_send_prepare (PQsendPrepare available since libpq 7.4)
- pg_send_query_params (PQsendQueryParams available since libpq 7.4)
- pg_set_error_verbosity (PQsetErrorVerbosity available since libpq 7.4)
- pg_transaction_status (PQtransactionStatus available since libpq 7.4)
The Windows libpq version is currently at version 11.4:

Follow-up of GH-14540
The PG_VERSION_NUM is not available in intended public PostgreSQL
headers unless the pg_config.h is included or the PostgreSQL server
development headers are installed separately. This instead resorts to
checking for the PGVerbosity enum value. The PQERRORS_SQLSTATE was added
to PostgreSQL 12.0. At the time of writing, on Windows, PostgreSQL is at 11.4 so
it is not defined there yet.
Using PQSocketPoll to poll on a connection's socket.
Returns immediatly is there no event expected on read and write.
Other than that, it is a thin wrapper on top of poll, thus reflecting
its return value.

pg_put_copy_data allows to send COPY commands to the server.
pg_put_copy_end signals the end of the n commands.
Both return 3 states ; 1, 0 and -1 when 1 is success, 0 the buffer queue
is full then -1 for errors.

Adding pg_send_flush_request.
Fix freeze after next execute pg_send_* on PQgetResult in _php_pgsql_link_has_results.
Set nonblocking for pipelining mode.
No flush client buffer in pg_send_* for pipelining mode.

Previously, pg_select did not allow unconditional selection, where an
empty ids array would result in a function failure.
This patch implements two changes:
- Make the ids array an optional parameter.
- Allow the ids array to be empty.
In both cases, unconditional selection happen, which is equivalent to
pg_query('SELECT * FROM <table>;').
Two test cases were added to test the aforementioned changes.

another level of context for pg_last_error/pg_result_error() to include
or not the context in those. PQSHOW_CONTEXT_ERRORS being the default.

- PGSQL_TRACE_SUPPRESS_TIMESTAMPS.
- PGSQL_TRACE_REGRESS_MODE to have a more verbose and observable
output to check possible regressions.

This is an error that slipped in via 8d37c37bcd.
pg_unescape_bytea() did not accept null in PHP 7.4, and it is not
meaningful for it to accept null now -- it will always fail, and now
with a misleading OOM message.
The same error condition is a ValueError in mysqli, be consistent.
Additionally, do not display the argument name for these errors.
As the signatures are overloaded, the argument name may not match
the meaning at all.
The implementation did not check for PQunescapeBytea failure
correctly, because it checked for a null pointer after estrndup,
which certainly cannot happen. Inspection of the PGunescapeBytea
implementation has shown that this function can only fail on OOM,
so let's check for that explicitly and remove false as a possible
return type.
While we're here, avoid an unnecessary copy of the result.
