  • How to load Additional Supplied Modules for Postgres on Windows

    I try to enable "fuzzystrmatch" function in Postgresql 8.3.9, following is my solution:

    1. DO NOT install Postgresql under the default "Progrem File" directory, because the it can't not recognize the white space inside the path! I switch to some directory not containing while space, like "C:/PostgreSQL/8.3/". I will use this as my Postgres home directory. I install and reinstall several times and figure out this isssue. Actually. it is a very common problem using software ported form Linux world.
    2. You will find lots of DLL files under "lib". But we should go to "share/contrib" directory. Run:
      • C:/PostgreSQL/8.3/bin>psql -d postgres -U postgres -f C:/PostgreSQL/8.3/share/contrib/fuzzystrmatch.sql
        SET
        CREATE FUNCTION
        CREATE FUNCTION
        CREATE FUNCTION
        CREATE FUNCTION
        CREATE FUNCTION
        CREATE FUNCTION
        CREATE FUNCTION
    3. You should note that this funtion must be specified to any database you want. It is not a global setting! Then try SELECT levenshtein('GUMBO', 'GAMBOL'); or SELECT name FROM element  WHERE difference(name, 'item') > 2;
    4. If you want to check out more fuzzy search, go to reference [1]. There will be another solution, please refer to [2].
    5. Next, I will try xml and full-text search functions.
