On the docs. Don't forget, PHP a) probably has a lot more users than we do, b) only keep one version of the docs
online,whilst we have many and c) have been doing this a lot longer than us.

See above. We do get useful comments as well as rubbish.

Here's a couple of example from my inbox this morning:

[pgsql-slavestothewww] Comment 2333 added to page install-upgrading.html of version 7.4

If you use pg_dump on an older version (say 7.1.x, 7.2.x, or 7.3.x) you will get complains from psql about carriage
returnsmust be represented as literal \r.  The workaround for this is to use the -d argument with pg_dump to dump as
insertstatements, but that makes restore ungodly slow (prohibitively slow in my case).  In one data test I did the
restoretook 4 days - not workable for a production SQL environment. 

The solution I found was to put together a perl script to clean the output of "pg_dump <<dbname>> > <<file>>" to change
carriagereturns to \r.  I'm sharing my script here in hopes someone finds it useful. 

-- BEGIN clean-pgdump.pl --
#!/usr/bin/perl -w

use strict;

my $file = shift @ARGV || '';
die "no input file specified\n" unless $file;

open(FILE, $file) || die "cannot read file: $!\n";
while (<FILE>) {  s'\r\\\n'\\r'go;  s'\r'\\r'go;
  print;
}
close(FILE);

exit;
-- END clean-pgdump.pl --

Execute the script with ./clean-pgdump.pl <<file>> > <<newfile>>
Then run "psql -d template1 -f <<newfile>>" to import




I think it's clear we need to moderate what gets on there and what doesn't (the first comment basically says 'I'm from
Baziland I like this site'). 

Whilst I'm on the subject I will also point out that early versions of the the idocs were un-moderated and we still
findgarbage in there from time to time. If anyone sees any, please email webmaster or pgsql-www with the url so we can
cleanit up. 

Regards, Dave.
