Kompilasi PL/Proxy dengan PostgresPlus Advance Server 9.1

1. Unduh Pl/Proxy.

wget http://pgfoundry.org/frs/download.php/3274/plproxy-2.4.tar.gz
tar -xvf plproxy-2.4.tar.gz
make PG_CONFIG=/opt/PostgresPlus/9.1AS/bin/pg_config
make intall PG_CONFIG=/opt/PostgresPlus/9.1AS/bin/pg_config

Note: Flex & Bison must be installed before compiling pl/proxy.

2. Setelah konfigurasi berhasil, Anda mendapatkan dua file, plproxy.so di $PGPATH/lib &plproxy–2.4.0.sql di $PGPATH/share/extension/ location.
Jalankan file .sql yang membuat call_handler &bahasa.

bash-4.1$ psql -p 5444 -U enterprisedb -d edb -f /opt/PostgresPlus/9.1AS/share/extension/plproxy--2.4.0.sql
CREATE FUNCTION
CREATE LANGUAGE
CREATE FUNCTION
CREATE FOREIGN DATA WRAPPER

Sekarang Anda dapat melihat bahasa yang diinstal.

edb=# dL
        List of languages
  Name   |    Owner     | Trusted
---------+--------------+---------
 edbspl  | enterprisedb | t
 plpgsql | enterprisedb | t
 plproxy | enterprisedb | f
(3 rows)

3. Mari kita uji kode sampel dengan pl/proxy.

create table users(username text,blog text);
insert into users values('Raghav','raghavt.blogspot.com');

CREATE or replace  FUNCTION get_user_blog(i_username text)
RETURNS SETOF text AS $$
    CONNECT 'dbname=edb';
    SELECT blog FROM users WHERE username = $1;
$$ LANGUAGE plproxy;

edb=# select * from get_user_blog('Raghav');
          get_user_blog
----------------------------------
 raghavt.blogspot.com
(1 rows)
