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 pkg-config (libpq.pc file) was added in PostgreSQL 9.3. This adds a
common setup M4 macro PHP_SETUP_PGSQL to find client PostgreSQL library
libpq on the system with pkg-config. If not found, check falls back to
pg_config to find the libpq and its headers in common locations as
before.
The PGSQL_CFLAGS and PGSQL_LIBS environment variables can override the
libpq installation paths:
./configure --with-pgsql --with-pdo-pgsql \
PGSQL_CFLAGS=-I/path/to/libpq \
PGSQL_LIBS="-L/path/to/libpq -lpq"
Passing manual, non-standard PostgreSQL installation path can be done
with configure option arguments:
./configure \
--with-pgsql=/any/path/to/postgresql \
--with-pdo-postgresql=/any/path/to/postgresql
If this DIR argument (PostgreSQL installation directory or path to the
pg_config) is passed, it takes precedence over the pkg-config, when
installed on the system.
This also removes the unused HAVE_LIBPQ symbol and passing the
PGSQL_INCLUDE and PGSQL_LIBDIR environment variable to configure in
favor of PGSQL_CFLAGS and PGSQL_LIBS.
Instead of the obsolete backticks the recommended $(...) is used when
invoking the pg_config.
Follow-up of GH-4235 (Use PKG_CHECK_MODULES to detect the pq library)
The pg_encoding_to_char is available in PostgreSQL since ~7.3 where also
the --enable-multibyte option was removed. PHP minimum PostgreSQL
version at this point is 9.1, which also has the pg_encoding_to_char
declaration in libpq-fe.h.
This removes conditional usage and the HAVE_PGSQL_WITH_MULTIBYTE_SUPPORT
symbol.
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.

Even if that header file is available, we better consider it private,
and don't include it. The information about whether SSL support is
enabled is now missing (`USE_(OPEN)SSL`), and it seems there is no
alternative way to get it (`PQinitSSL()` is always defined), so we
remove it from the PHP info. Furthermore, the `PG_VERSION` and
`PG_VERSION_STR` macros are no longer available, but as of libpq 9.1
there is `PQlibVersion()` which allows us to construct `PG_VERSION` in
a most likely backwards compatible manner. The additional information
available through `PG_VERSION_STR` is lost, though, so we define
`PGSQL_LIBPQ_VERSION_STR` basically as alias of `PGSQL_LIBPQ_VERSION`,
and deprecate it right away.
Since we are now requiring at least libpq 9.1, we can remove some
further compatibility code and additional checks.
Regarding the raised requirements: official support for PostGreSQL 9.0
ended on 2015-10-08, and even CentOS 7 already has PostGreSQL 9.2, so
this is not supposed to be too much of an issue.
We can safely assume that users have at the very least libpq 7.4, for
which official support ended on 2010-10-01; even CentOS 6 has 8.4 now.
It is also noteworthy that PDO_PGSQL already requires libpq 7.4 or
later.
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

Some editors utilizing .editorconfig automatically trim whitespaces. For
convenience this patch removes whitespaces in certain build files:
- ext/*/config*.m4
- configure.ac
- acinclude.m4
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
# The version in libpq is newer and faster than the one in PHP, but it is
