Hello!
I'm willing to implement the 'Add support for interface/ipaddress binding to libpq' feature from the ToDo list.
Actually, the 'ipaddress' part.
For this I'm planning to do the following:
- Introduce 'sourceaddr' parameter keyword and 'PGSOURCEADDR' env var which can be used to specify local IPv4 or IPv6 ipaddress to bind to
- Silently ignore the parameter's value in case of Unix-domain communication with database
- Use BLOCKING bind() call to bind communication socket to specified local ipaddress in two functions:
src/interfaces/libpq/fe-connect.c@internal_cancel()
src/interfaces/libpq/fe-connect.c@PQconnectPoll()
Is this enough or I missed something?
WBR, Grigory.
