Bug in contrib/intagg int_array_enum() ?
I'm seeing some strange behaviour using the int_array_enum function in
contrib/intagg.
It seems when i set the array to an empty array by hand doing update set
level_2_ids = '{}' then int_array_enum generates some odd data:
slo=> select * from (select int_array_enum(level_2_ids) as l2,level_2_ids from cache where key_id = 900) as x where level_2_ids = '{}';
l2 | level_2_ids

0 | {}
23 | {}
1 | {}
0 | {}

AFAICT, intagg is completely unready to deal with arrays of other than
one dimension; nor has it got any error checks to notice when the input
is not 1-D. '{}' is treated as zero-dimensional ...

Hi everyone,
I run into problem where pg_pconnect (in php script) failed to get
connection to the postgres server even when the server is actually
running because the server is too busy (serving too many requests).
So I want to check from php script if postgres server is running. The
only way I could think of to is telnet the server on port 5432 (where
postgres is listening).
Does someone know a better way to check if postgres server is running?
thanks

Ah, so then how do I construct a one-dimensional zero-sized array?

thanks for the quick reply Darren, but you can't do this if the web
server is running on a different server than the database, right?

netstat -anp | grep postmaster
This will tell you if postmater is listening on the port.
If you do not have root access then
netstat -an | grep 5432

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

If you have command line access to the machine with the Database you can
run the command from there.
Sorry about that i should have read the mail more
