Re: [BUGS] BUG #3504: Some listening sessions never return from writing, problems ensue
Hey, I found something that finally clears netstat's recv-q with async notifies. I don't quite understand what's going on, so any enlightenment would be greatly appreciated. As near as I can figure, the client doesn't appear to read the notifies until it sends a notify of its own. Then it reads all pending notifies at once and clears the recv-q. For instance, I can open up two connections on my test server and illustrate the problem. Here's the netstat before everything.

To me it looks like the first psql session isn't prepared to gather async notifies (checking...) indeed, psql only checks for async notifies when issuing commands (you don't have to issue a NOTIFY in "Connection 1" to receive the pending notifies -- *any* request directed to the server would do). > Any ideas?

Re: [BUGS] error while starting database
PostgreSQL version 7.0 is really, really out of date, but as far as I
know, it should still work.
I generally use "ps -ax | grep postges" to see if there is a postgres
process running. Also, I use "netstat -a" to see open sockets and
listening servers.
Have you removed the socket file in /tmp and tried to start the
server? You may also want to check the server log to see if there is
any indication of why it crashed. Once you clean up the residue from
the server that abended, you'll be able to start it again, unless
there are serious problems with the database. I've only seen one
case where I couldn't get the server restarted, though, and that was
after a hard drive failure caused corruption in several files. Even
then, I was able to recover everything.
BTW: the socket file ("/tmp/.s.PGSQL.5432") will be a hidden file.
You'll need to "ls -a /tmp" to see it. You can just "rm -f /
tmp/.s.PGSQL.5432" as root and that should clean it up for you.
p.s. This is not a bug, and even if it was, I'm sure version 7.0 is
no longer supported. You may want to use a different list if you
require additional assistance.

At first I thought that was a typo, but if psql really spelled its error message just like that, it must indeed be 7.0 or older :-(. Do yourself a favor and get onto a newer version, NOW. Not tomorrow. There are hundreds if not thousands of known bugs in 7.0 that are fixed in more modern versions. Some of them *will* destroy your data. As for getting out of the immediate problem, it looks like there is something wrong with the directory that PG wants to put its socket file into.

[BUGS] BUG #3548: When quickly switching between databases the server lags behind
The following bug has been logged online:
Bug reference: 3548
Logged by: Daniel Heyder
Email address: [EMAIL PROTECTED]
PostgreSQL version: 8.2.4
Operating system: Linux (Red Hat EL4 Update 4 + PostgreSQL 8.2.4 update +
compat libraries)
Description:When quickly switching between databases the server lags
behind
Details:
Hi,
when I do quick PQconnectdb give the connection something to do PQfinish the
connection and PQconnectdb to another database the database server does not
keep up, neither does PQconnectdb or PQfinish block until the work is
complete. This is annoying when I want to delete the still working database.
(Causes an error as it is still in use.)
Here some code which demonstrates the problem (make sure it is the only
process accessing the database):
#include
#include
int main()
{
char *pq_db;
char *tb_db;
PGconn *conn;
PGresult *res;
for (int x = 0; x < 2000; x++)
{
conn = PQconnectdb("host=127.0.0.1 dbname=postgres port=5432");
pq_db = PQdb(conn);
res = PQexec(conn, "SELECT * FROM pg_catalog.pg_stat_activity ORDER BY
usename, procpid;");
tb_db = PQgetvalue(res, 0, 1);
if (strcmp(pq_db, tb_db) != 0)
{
fprintf(stderr, "* ERROR WRONG DATABASE OPEN (pq=%s, tb=%s)
**\n", pq_db, tb_db);
return 1;
}
PQclear(res);
PQexec(conn, "CREATE TABLE x1 (x integer PRIMARY KEY, y integer,z
timestamp without time zone,u timestamp without time zone);");
PQexec(conn, "CREATE TABLE x2 (x integer PRIMARY KEY, y integer,z
timestamp without time zone,u timestamp without time zone);");
PQexec(conn, "CREATE TABLE x3 (x integer PRIMARY KEY, y integer,z
timestamp without time zone,u timestamp without time zone);");
PQexec(conn, "CREATE TABLE x4 (x integer PRIMARY KEY, y integer,z
timestamp without time zone,u timestamp without time zone);");
PQexec(conn, "CREATE TABLE x5 (x integer PRIMARY KEY, y integer,z
timestamp without time zone,u timestamp without time zone);");

timestamp without time zone,u timestamp without time zone);");

timestamp without time zone,u timestamp without time zone);");
PQexec(conn, "CREATE TABLE x8 (x integer PRIMARY KEY, y integer,z
timestamp without time zone,u timestamp without time zone);");
PQexec(conn, "CREATE TABLE x9 (x integer PRIMARY KEY, y integer,z

PQexec(conn, "DROP TABLE x9");
PQfinish(conn);
conn = PQconnectdb("host=127.0.0.1 dbname=template1 user=csntool

pq_db = PQdb(conn);
res = PQexec(conn, "SELECT * FROM pg_catalog.pg_stat_activity ORDER BY

{
fprintf(stderr, "* ERROR WRONG DATABASE OPEN (pq=%s, tb=%s)

return 1;
}
PQclear(res);

Re: [BUGS] error while starting database
If it is true that listing /tmp (ls -a /tmp) returns no such file or
directory, then that may be the problem. You should have a world-
writable /tmp folder, as Tom already pointed out. Also, an update to
a more stable version of PostgreSQL is still highly recommended.
