MacOS Mojave and pg_connect with SSL - php

Question

I'm running Mac OS X with Mojave and default Apache and PHP.
I'm trying to connect to a PostgreSQL with SSL/TLS, but are getting the error:
Warning: pg_pconnect(): Unable to connect to PostgreSQL server: sslmode value "require" invalid when SSL support is not compiled in in ..
However, running pg_config --configure does show the '--with-openssl' flag.
Running phpinfo however shows under pgsql that SSL is disabled.
But directly from the terminal I am able to use command line psql with SSL.

Answer 1

I was also stuck on the same issue, here's how I solved it
The default PHP of MacOS 10.14 (Mojave) doesn't have SSL enabled in its php pgsql extension
To manually install SSL certificate into the php pgsql extension would be possible but
troublesome
Instead, you can install a new version of php, which would indeed install all it's extensions again also with a php postgres extension with ssl enabled
First install homebrew if you don't have it, then install php as shown below
I installed php 7.3, as I had Catalina it came with 7.3.11 (it got upgraded to 7.3.21)
brew update
brew install php#7.3
brew link php#7.3
If you updated Mojave to Catalina, you may want to also add this after the above is done
brew link php#7.3 --force
After the above is done you just need to link it to your $PATH which can be done as:
echo 'export PATH="/usr/local/opt/php#7.3/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/php#7.3/sbinbin:$PATH"' >> ~/.bash_profile
If you updated Mojave to Catalina, instead of the above do this
(since Catalina changed default shell to Zsh)
echo 'export PATH="/usr/local/opt/php#7.3/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/php#7.3/sbin:$PATH"' >> ~/.zshrc
Reload the terminal or open a new one, type in
php -v (the version should be changed)
And then type php -i, goto pgsql section
pgsql
PostgreSQL Support => enabled
PostgreSQL(libpq) Version => 12.3
PostgreSQL(libpq) => PostgreSQL 12.3 on x86_64-apple-darwin19.4.0, compiled by Apple
clang version 11.0.3 (clang-1103.0.32.59), 64-bit
Multibyte character support => enabled
SSL support => enabled
Active Persistent Links => 0
Active Links => 0
Directive => Local Value => Master Value
pgsql.allow_persistent => On => On
pgsql.auto_reset_persistent => Off => Off
pgsql.ignore_notice => Off => Off
pgsql.log_notice => Off => Off
pgsql.max_links => Unlimited => Unlimited
pgsql.max_persistent => Unlimited => Unlimited
You should see SSL support enabled.
