Bug reference: 1110
Logged by: Michael Enke
Email address: michael.enke@wincor-nixdorf.com
PostgreSQL version: 7.4
Operating system: Linux
Description: psql -h localhost consults the nameservice
Details:
If I call "psql -h localhost" it is very slow
compared to "psql -h 127.0.0.1" since for "localhost"
the nameservice is consulted.
It is reproducable best in a loop. Call 50 times:
"psql -h localhost" takes 6 seconds
"psql -h 127.0.0.1" takes 0.6 seconds
This was not the case for psql from version 7.3
May be this has something to do with changes for IP v6.
