This error has just started popping when I run queries against TABLE_A .......
ERROR: XX001: invalid page in block 38 of relation pg_tblspc/16402/PG_14_202107181/16404/125828
If I try a very simple query against the same table for example SELECT * FROM TABLE_A I get a similar error....
ERROR: invalid memory alloc request size 18446744073709551613
SQL state: XX000
Or another similar query select count(*) from TABLE_A gives me....
ERROR: could not access status of transaction 917520
DETAIL: Could not open file "pg_xact/0000": No such file or directory.
SQL state: 58P01
Based on this thread I tried this fix....
SET zero_damaged_pages = on;
VACUUM full TABLE_A;
REINDEX TABLE TABLE_A;
The 2nd command, VACUUM full TABLE_A produced another related error....
ERROR: found xmax 16384 from before relfrozenxid 379279265
SQL state: XX001
I think all these problems boil down to a simple case of file corruption at the OS level. I do have the ability to drop and re-create this table, but before I start I'd like to know if there's a quicker/simpler solution, and if there's any way of stopping this from happening again.

When I attempt to copy a CSV from S3 into a new table in Redshift (which normally works for other tables) I get this error
ERROR: Load into table 'table_name' failed. Check 'stl_load_errors'
system table for details.
But, when I run the standard query to investigate stl_load_errors
SELECT errors.tbl, info.table_id::integer, info.table_id, *
FROM stl_load_errors errors
INNER JOIN svv_table_info info
ON errors.tbl = info.table_id
I don't see any results related to this COPY. I see errors from previous failed COPY commands, but none related to the most recent one that I am interested in.
Please make sure that you are querying stl_load_errors table with same user you are performing COPY command. You can also try to avoid using ssv_table_info table in query or change INNER to LEFT join.
I am using a PostgreSQL DB. I have two tables, namely company and bl_location. I have a field location_id in both tables. Now I am trying to copy the value of location_id from bl_location to company. The primary key of company is company_id and it is stored in bl_location too. I am trying the following query:
UPDATE company
SET location_id = bl_location.location_id
from bl_location
where company.company_id = bl_location.company_id;
using the syntax I found online:
update table1
set col1 = . . .
from table2
where table1.id = table2.table1_id
But I am getting the following in the console of the pgAdmin tool:
ERROR: current transaction is aborted, commands ignored until end of transaction block
********** Error **********
ERROR: current transaction is aborted, commands ignored until end of transaction block
SQL state: 25P02
I cannot figure out what is wrong with my query.
RCA : This issue happens when last transitions ended up with error and not rolled back
FIX : psql > ROLLBACK
if you're using PGAdmin click on rollback & enable auto rollback option
Whether you are aware of it or not, your statement is running inside an explicit transaction, and one of the preceeding statements is the same transaction must have caused an error.
To debug this, consider setting log_statement = 'all' so that all statments get logged. By tracing all statements from the same backend PID you will be able to identify the culprit.
I recently hit a Postgres error (my DB corrupted), basically, some rows on the DB duplicated (along with the primary key). Before I keep going, these are the errors addressed in this post:
ERROR: uncommitted xmin 393410960 from before xid cutoff 393413059 needs to be frozen
OR
ERROR: failed to find parent tuple for heap-only tuple at (3,8) in table "your_table"
Obviously, the xmin value of 393410960, the cut-off value of 393413059 and the ctid value of (3,8) could be different in your case.
How I get these errors:
If you want to get these errors (and you have this problem) this is how you could find them:
your_db=# VACUUM FULL your_table;
ERROR: uncommitted xmin 393410960 from before xid cutoff 393413059 needs to be frozen
And to get the second error:
your_db=# REINDEX TABLE your_table;
ERROR: failed to find parent tuple for heap-only tuple at (3,8) in table "your_table"
DON'T PANIC! The solution to this is given below :)
Before you read this, please note I take no responsibility for data loss or corruption or any problems this causes!
I'd suggest you back up everything! But don't do pgdump, do a full filesystem backup. Use rsync and put it somewhere else.
There also may be other solutions out there, so don't do this one first before doing more research. I can state, however, that this did work for me.
So in order to fix this, I followed the advice given in the post at:
http://www.postgresql-archive.org/BUG-10189-Limit-in-9-3-4-no-longer-works-when-ordering-using-a-composite-multi-type-index-td5802079.html
Basically, what I did was the following:
your_db=# BEGIN;
BEGIN
your_db=# DELETE FROM your_table WHERE ctid='(3,8)';
DELETE 1
your_db=# END;
COMMIT
your_db=# VACUUM FULL your_table;
VACUUM
your_db=# REINDEX TABLE your_table;
REINDEX
Only the lines that start with your_db=# are ones that I wrote. So what you can see there is that I deleted the offending row and then ran a reindex. If that fails, you delete the next offending row and reindex until it succeeds.
Hope this helps.
I am working on a view which this is its sql
-- DROP VIEW bd_segment_id;
CREATE OR REPLACE VIEW bd_segment_id AS
SELECT final.gid,
row_number() OVER (ORDER BY final.gid) AS row_number,
degrees(st_azimuth(ff.sp, ff.ep) - 1.57079633::double precision) AS az_deg,
st_length(ff.st_makeline) AS st_length,
ff.st_makeline
FROM bd_segment_geom ff
JOIN final ON st_touches(ff.st_makeline, final.geom)
GROUP BY final.gid, ff.sp, ff.ep, ff.st_makeline;
ALTER TABLE bd_segment_id
OWNER TO postgres;
while running each query of this table I have faced this error
ERROR: GEOSTouches: TopologyException: side location conflict at 553655.77720000315 3474241.5185000021

Is there any way for sql to pass errors and continues to do the rest of sql?I know the problem is an internal error but I want sql jump of it..
I have searched and found this in section 39.6.6. Trapping Errors is says how we can use an EXCEPTION clause but I don't know how to write handler_statements that says sql to continue.
I need sth like try catch in C# or jave
can some one please help me with this problem?
thank you
I am working on windows, and have enabled the extension postgis, pgrouting on database. I have postgreSQL 9.4 installed and i am using the data from boundless workshop (http://workshops.boundlessgeo.com/tutorial-routing/).
SELECT pgr_nodeNetwork('edges',0.001,'geom','gid','noded')
when I run this query, it runs about 1minute and after that time it results in FAIL. How can I solve this issue? My pgr_createTopology query has been successfully run.

I ran into this issue in my project and I was stuck on it for hours trying to figure out what was causing it AND how to fix it. I will describe my situation and how I fixed it so hopefully, it helps someone else in the future.
I am using ogr2ogr to import a Shapefile into my database and I was using the -nlt PROMOTE_TO_MULTI as one of my arguments during my import; this caused my geometries to be imported as MultiLineStrings.
From the behavior I've observed and what others have mentioned (and more people), the pgr_nodeNetwork() function does not play nicely with MutliLineStrings.
Since MultiLineStrings won't work for routing, I took the SQL from dkastl's answer and ran it on my data to see if I actually needed MultiLineStrings or if I could just work with LineStrings.
SELECT
COUNT(
CASE WHEN ST_NumGeometries(geom) > 1 THEN 1 END
) AS multi,
COUNT(geom) AS total
FROM network_nodes;
After running that, I found that I had zero need for MultiLineStrings so I reimported my Shapefile with ogr2ogr using -nlt LINESTRING instead and then was able to run pgr_nodeNetwork() without problems.
