Missing libraries when upgrading to PostGIS 2.1 and PostgreSQL 9.3.1 using homebrew

问题

In the process of upgrading my PostgreSQL from version 9.2.4 to 9.3.1 (via homebrew on OS X) I came across an odd problem. These are the steps I took so far

PostgreSQL, PostGIS and required libraries installed (no errors)
run initdb on the new database
stopped both servers
running pg_upgrade

pg_upgrade performs the necessary checks, creates dumps of the old cluster, but when importing into the new cluster I get the following error:

> ./pg_upgrade -b /usr/local/Cellar/postgresql/9.2.4/bin/ -B /usr/local/Cellar/postgresql/9.3.1/bin -d /usr/local/var/postgres/ -D /usr/local/var/postgres9.3.1 -u postgres

Your installation references loadable libraries that are missing from the
new installation.  You can add these libraries to the new installation,
or remove the functions using them from the old installation.  A list of
problem libraries is in the file:
    loadable_libraries.txt

Failure, exiting

It appears as though PostgreSQL 9.3.1 tries to use PostGIS 2.0, which is not compatible

Could not load library "$libdir/postgis-2.0"
ERROR:  could not access file "$libdir/postgis-2.0": No such file or directory

Could not load library "$libdir/rtpostgis-2.0"
ERROR:  could not access file "$libdir/rtpostgis-2.0": No such file or directory

Has anyone run into the same problem?

回答1:

I recently ran into this problem and re-installing postgis worked for me. That is, go to the folder in which you tar'ed the source file (if you installed postgis from source) and re-run:

./configure
make
sudo make install

If you've installed the latest version of postgresql, postgis should install into the new postgresql's extension folder:

/usr/share/postgresql/x.x/extension/

To check, run:

sudo su -l postgres

psql template1 -p 5433

SELECT name, default_version,installed_version 
FROM pg_available_extensions WHERE name LIKE 'postgis%' ;

If postgis has successfully installed, you should see the version number indicated in the "installed" column. Now when you try running the pg_upgrade command, everything should work fine.

Hope this helps.
