how to install fuzzystrmatch.sql pg_trgm.sql on postgresql on mac os x

Question

I have installed postgresql according to this, but I also need fuzzy string match functions, but I have no idea how to install these.

Solution 1

For the Mac, the .sql files are in a folder such as /Library/PostgreSQL/8.3/share/postgresql/contrib

Solution 2

If you are looking for levenshtein or other functions in fuzzystrmatch package in postgresql 9.1, just do this:

# Login with postgres user and:
psql my_database -U postgres
# Enter the postgres password and type in the psql shell:
CREATE EXTENSION fuzzystrmatch;

Done.

Solution 3

If you can't find that extension, it's possible you didn't install postgres contrib.

for instance, on centos style os's:

yum install postgresql93-contrib

Solution 4

Based on the answer here in the context of a Rails migration, all it takes is:

create extension fuzzystrmatch;
create extension pg_trgm;

Solution 5

Usually with a sql file full of functions, it is something like this:

cat fuzzystrmatch.sql | psql {database name}

Ask the guys from "PostgreSQL for Mac".

For me, it was in /Library/PostgresPlus/8.3/share/contrib .
