Looks like libpq is missing on macOS? I think installing postgresql in brew just gets you the server, not the client. 🤔

@Qard whats really strange is that the x86 macos build did work 🤔

I will have a look later why that might be the case.

Ah, yeah, that is strange.

I'm pretty sure I actually had it building at one point locally. I did test against a bunch of other extensions, but we reduced the set down to just what was needed to get the main frameworks working. (Wordpress, Laravel, etc.)

Of course we're happy to support additional extensions as users have need of them though, so we can for sure get this landed once CI works. 🙂

I managed to get the PHP build locally. But I used Postgres 16 I see now. I decided to use 14 because that is what is inside the Ubuntu side. Let me try.

Success:

checking for libpq >= 10.0... no
checking for pg_config... not found
configure: error: in '/Users/tsc/datenknoten/dev/php-src':
configure: error: Cannot find libpq-fe.h or pq library (libpq). Please specify the correct
PostgreSQL installation path with environment variables PGSQL_CFLAGS and
PGSQL_LIBS or provide the PostgreSQL installation directory.
See 'config.log' for more details

Let me try 16.

Minor docs nit, but otherwise LGTM. 🙂
