Install PostgreSQL PHP extensions on Mac OS X

Dudeeeeeee you save my life :D

You saved me! I owe you a beer haha

Thank you!

Freaking amazing. This is the best thing since sliced bread. Thanks a billion

Very Helpful. Thanks you helpful to get the pgsql module installed.

Note that on OS/X the location of the php.ini for the Web application and for the php command line is different -

On OS/X Yosemite:

/usr/local/php5/lib/php.ini - php.ini for the Web app
/usr/local/etc/php/7.1/php.ini - php.ini for the php command line (if you are using php 7.1 YMMV)
If you are using Postgres you will need to specify the location of the pdo_pgsql extension like:
extension="/usr/local/php/extensions/pdo_pgsql.so" (again YMMV depending on your system)

xcode-select: error: command line tools are already installed, use "Software Update" to install updates
pdo_pgsql
pgsql
Already up-to-date.
Warning: autoconf 2.69 is already installed and up-to-date

@mattjis since macOS High Sierra pgsql is included in the standard PHP instalation, so you don't need this workaround anymore.

If you take a look at your log, lines 2 and 3 show that you actually have pdo_pgsql and pgsql installed [from here]. Check yourself by typing php -m | grep pgsql or php --info | grep PostgreSQL in console.
