Postgresql Out Of Memory
am getting this error consistently after running for around 400s: ERROR: out of shared memory SQL state: 53200 Hint: You might need to increase max_locks_per_transaction. Context: SQL statement "CREATE TABLE tmp_cands AS SELECT d.premise_id AS uid, d.* FROM tmp_cands_1 AS c INNER JOIN nlpg.match_data AS d ON c.pid = d.premise_id" PL/pgSQL function "get_match" line 61 at SQL statement I have increased the max_locks_per_transaction to 10000 to no avail. Please can anyone tell me how I can find out more about this error and/or what I might do to solve it. I was thinking that it might be related to the creation of tables that may not be getting dropped until the query exited. In which case I was thinking of trying to use EXECUTE ''DROP/CREATE/ ....'' at the cost of no query planning benefits, but this is mostly a guess.. Any help/suggestions much appreciated. I have pasted the offending portions of the code below for luck. Cheers, Tom ------------------------------ -- Inserts matches for input address into match table and returns number o

Hello Guys, We are trying to restart postgres migrate from Oracle to Postgres. One of the major requirement of our database is the ability to generate XML feeds and some of our XML files are in the order of 500MB+. We are getting "Out of Memory" errors when doing an update on a table. Here is some detail on the error: ------------------------------------ update test_text3 set test=test||test The table test_text3 contains only one record, the column test contains a string containing 382,637,520 characters (around 300+ MB) Error https://www.postgresql.org/message-id/2C6372A5-92DB-43C5-8273-E8D4F60B4E3C@gmail.com Message: ERROR: out of memory DETAIL: Failed on request of size 765275088.

One of the major requirement of our database is the ability to generate XML feeds and some of our XML files are in the order of 500MB+. Considering future scalability we are trying to see how much data can be stored in a "text" column and written to the file system as we found PostgreSQL's COPY command a very efficient way of writing date to a file.

However I keep getting the following error: ERROR: out of memory SQL state: 53200 Detail: Failed on request of out of memory size 1048576. This would suggest there is some memory limit set in the config file to only 1MB. However, I have set my work_mem to 16MB and my shared_mem to 500MB in the config file and reloaded it, plus completely restarted the server. I have also tried manually setting the work_mem for the session. The really annoying thing is that I have used this process to import a much larger dataset into PostGIS on a Netbook computer with considerably less physical memory. I vaguely remember having to tweak some setting to do it but for the life of me I can't remember what it was and the config file looks like the original factory settings! So, if it is not the work_mem that is at fault, which setting should I adjust? (I'm using PostGIS 2 and Postgresql 9.1 on Windows 7 32 bit).

I assume you are getting the error for a DBMS_OUTPUT.PUT_LINE call. If so, try splitting your message into shorter messages of 2048 bytes or less. 3 Jun 2008 04:53:36 Subject: Re:Error SQL state: 53200 sreenivas_m Member Joined: 5 Feb 2008 23:23:22 Messages: 29 Offline Hi Muhammad problem solved.
