commit 9d1f44113dd82773e95f15061ad4bf2ad7acf4ce
Author: Itagaki Takahiro <itagaki.takahiro@gmail.com>
Date: Thu Jun 03 09:45:47 2010 +0000
First released in: 9.0.0, 8.0.26, 8.1.22, 8.2.18, 8.3.12, 8.4.5
Fix dblink to treat connection names longer than NAMEDATALEN-2 (62 bytes).
Now long names are adjusted with truncate_identifier() and NOTICE messages
are raised if names are actually truncated.
Backported to release 8.0.
