How to use hstore of postgreslq-9.0 with MacPorts

hstore is contained in the archive of source for postgresql, but MacPorts doesn't provide it as is. You need to change the Portfile of postgresql90.

sudo port edit postgresql90

warning on my env, I got following error message when to begin editting. It's not major problem for hstore installation.

Error detected while processing /Users/tsakuma/.tealmole/vim/bundle/unite.vim/plugin/unite.vim:
line   34:
"sudo vim" is detected. Please use sudo.vim or other plugins instead.
line   35:
unite.vim is disabled.
Press ENTER or type command to continue

Change a line for contribs.

-set contribs "adminpack auto_explain… +set contribs "hstore adminpack auto_explain…

Install the server.

$ sudo port install postgresql90
$ sudo port install postgresql90-server

From now, will express how to make sure hstore setup.

Initialize a database directory, start a new server process and create a new database.

$ sudo mkdir -p /opt/local/var/db/postgresql90/defaultdb
$ sudo chown postgres:postgres /opt/local/var/db/postgresql90/defaultdb
$ sudo su postgres -c '/opt/local/lib/postgresql90/bin/initdb -D /opt/local/var/db/postgresql90/defaultdb'
$ sudo su postgres -c '/opt/local/lib/postgresql90/bin/pg_ctl -D /opt/local/var/db/postgresql90/defaultdb start'
$ echo 'create database yourdb' |  psql -h localhost -U postgres

Finally, you can execute queries to set up hstore.

$ cat /opt/local/share/postgresql90/contrib/hstore.sql | psql -h localhost -U postgres yourdb

Try to check if it works.

$ psql -h localhost -U postgres
yourdb=> create table foo (vals hstore);
CREATE TABLE

Actually, I'd like to import some records from heroku, but it used hstore. Setting up hstore on my local env cost me a lot of effort...

If you ran into next error message by executing initdb, change directory to /tmp by cd /tmp and try it again.

shell-init: error retrieving current directory: getcwd: cannot access parent directories: Permission denied
could not identify current directory: Permission denied
could not identify current directory: Permission denied
could not identify current directory: Permission denied
The program "postgres" is needed by pg_ctl but was not found in the
same directory as "pg_ctl".

That seems a workaround from https://trac.macports.org/ticket/18024.
