In on OSX and I upgraded homebrew which upgraded me to postgres 9.3.
Now postgres won’t start because the old database is no longer compatible.
I found some promising instructions here:
But I get stuck on running this:
pg_upgrade -d /usr/local/var/postgres -D /usr/local/var/postgres9.3 -b
/usr/local/Cellar/postgresql/9.2.2/bin/ -B
/usr/local/Cellar/postgresql/9.3.4/bin/ -v
(
)
The content of loadable_libraries.txt is this::
Could not load library "$libdir/json_enhancements"
ERROR: could not access file "$libdir/json_enhancements": No such file or
directory
Yes, I had json_enhancement installed when I was using postgres 9.2. But I
don’t need that any more in 9.3 because json_enhancements was a backport
for 9.2.
The file is still there:
/usr/local/Cellar/postgresql/9.2.2/lib/json_enhancements.so
So, I can’t upgrade because I don’t have json_enhancements installed in
9.3. Which is not possible.
And I can’t upgrade by deleting ./lib/json_enhancements.so
./share/postgresql/extension/json_enhancements--1.0.0.sql and
./share/postgresql/extension/json_enhancements.control
How to get out of this pickle?
By the way, the database that I think I have it installed on is a database
I can do without. But I can’t simply `dropdb
a_database_with_json_enhancements_installed` because dropdb doesn’t work
any more of course.
