PostgreSQL version: 10.6
Operating system:   Mac OS X El Capitan 10.11.6
Description:

Upon a reinstall of 10.6.1 over 10.6, I try to add the hstore extension:

# create extension hstore;
ERROR:  could not open extension control file
"/usr/local/Cellar/postgresql@10/10.6/share/postgresql@10/extension/hstore.control":
No such file or directory

So /usr/local/Cellar/postgresql@10/10.6 is now
/usr/local/Cellar/postgresql@10/10.6_1 so the build calls are mis-pointed.
