Lets say that due to some corruption, automatic recovery is triggered by postgres. This results in "redo start at 0/9A3F58" as I can in the database logs. As part of the recovery, I suppose it would try to insert the records for a table. Does it cause database insert triggers for that table to be executed as well. We are using postgres 8.4.

No, replay from the write-ahead logs absolutely do not cause triggers to fire. In fact, they can't because the write-ahead logs store block level changes, not row-level changes, and have no idea which SQL statement changed which row.

I have restored a backup from psql server A to psql server B. When the postgresql service starts on server B, the log below is produced. From what I read the invalid record length message is not a problem, just an indicator that the end of the last WAL file was reached.
However, when I attempt to run 'psql' it gives a fatal error that the database is starting up. (I waited over an hour and still in that state). I still can't run psql. Note that standby.signal file is present on B, in case that matters.
What does this mean, and how do I fix it? Or is this normal while the standby.signal file is present?

Somebody deleted crucial WAL files (to free space?), and now your cluster is corrupted
Restore from backup. If you have no backup, running pg_resetwal is an option, since it seems there was a clean shutdown.
I have edited my pg_hba file and copied it to server and restarted the services by "sudo service postgresql restart" but after that the server is not connecting.
Showing the below error, Your database returned: "Connection to 138.2xx.1xx.xx:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections."
The Jenkins job and data visualization tools are failing which was working fine previously. What could be the reason.

Do i need to restart the entire server?
Can anyone please help me to resolve this.
I'm running a postgres server locally on my computer and it seems that even the simple queries like the one below is giving me an EOF detected error.
For instance, this query
ALTER TABLE maintab ADD COLUMN testing numeric;
UPDATE maintab SET testing = numeric1 * numeric2;
And similar activities will throw an EOF error. I'm also running PostGIS with QGIS and my spatial queries, no matter how simple, will throw this error.
I've look around at forums and documentation but nothing can seem to help solve this problem. Is there anything I can do to stop this?
EDIT
I ran a check on my error logs after doing some Googling. Found these logs, not sure what to make of them

i am run pg_dump on my vps server, it throw me error:
pg_dump: [archiver (db)] query failed: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
pg_dump: [archiver (db)] query was: SELECT
( SELECT alias FROM pg_catalog.ts_token_type('22171'::pg_catalog.oid) AS t
WHERE t.tokid = m.maptokentype ) AS tokenname,
m.mapdict::pg_catalog.regdictionary AS dictname
FROM pg_catalog.pg_ts_config_map AS m
WHERE m.mapcfg = '22172'
ORDER BY m.mapcfg, m.maptokentype, m.mapseqno
Then I notice the sql on the above error:
SELECT
( SELECT alias FROM pg_catalog.ts_token_type('22171'::pg_catalog.oid) AS t
WHERE t.tokid = m.maptokentype ) AS tokenname,
m.mapdict::pg_catalog.regdictionary AS dictname
FROM pg_catalog.pg_ts_config_map AS m
WHERE m.mapcfg = '22172'
ORDER BY m.mapcfg, m.maptokentype, m.mapseqno
So I try to run SELECT alias FROM pg_catalog.ts_token_type('22171'::pg_catalog.oid) on psql
So it throw me error:
pzz_development=# SELECT alias FROM pg_catalog.ts_token_type('22171'::pg_catalog.oid);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

How can I figure out the problem, and dump my data properly?
