pgsocket: Extension for Simple TCP/IP Socket Client

pgsocket is an extension for PostgreSQL server to send bytes to remote TCP/IP socket server. For the first version only single function provided for one way data send in bytearray.

This extension is compiled in Linux against PostgreSQL version 10.

Download source code from https://github.com/AbdulYadi/pgsocket. Build in Linux as usual:
$ make clean
$ make
$ make install

On successful compilation, install this extension in PostgreSQL environment
$ create extension pgsocket

Let us send bytes to –for example– host with IP address nnn.nnn.nnn.nnn, port 9090, send time out 30 seconds, messages “Hello”
$ select pgsocketsend(‘nnn.nnn.nnn.nnn’, 9090, 30, (E’\\x’ || encode(‘Hello’, ‘hex’))::bytea);

Or using address host name instead of IP address
$ select pgsocketsend(‘thesocketserver’, 9090, 30, (E’\\x’ || encode(‘Hello’, ‘hex’))::bytea);

Now, sending text from a table to remote TCP/IP socket server is easy. Assuming there is a table words:
id    txt
——————–
1    Life is easy
2    with PostgreSQL
just do:
$ select pgsocketsend(‘thesocketserver’, 9090, 30, (E’\\x’ || encode(t.txt, ‘hex’))::bytea)
from words t WHERE t.id = 1;
