I'm trying to migrate from mysql 5.7 to Postgres 14 with this command
pgloader mysql://root:pass#host/db postgresql://supabase_admin:pass#localhost:5433/db
but I get this error
2022-11-16T12:56:50.633053-05:00 ERROR A thread failed with error: Corrupt NEXT-chain in #<HASH-TABLE :TEST EQUAL :COUNT 8 {700E9EBA63}>. This is probably caused by multiple threads accessing the same hash-table without locking.
I do not understand this at all. How can I get around this?

My Java application interacts with PostgreSQL via MyBatis.
From multiple threads it executes this request
select *
from v_packet_unread
limit 1000
for update skip locked
and sometimes gets ERROR: could not serialize access due to concurrent update.
As I remember this error occurs in case of optimistic update, and here I use just SELECT, not even an UPDATE, and cannot explain what is going on.
v_packet_unread - is a simple view joining two small tables (2 columns per each) without any hidden effects (like triggers of function calls).
Could you help me to find out the reason of this behavior and how to avoid that?

Versions:
PostgreSQL 12.5 on x86_64-redhat-linux-gnu,

That can happen if you are running in a transaction with isolation level REPEATABLE READ or above: if you try to lock a row that has been modified concurrently by a different transaction since your transaction started, you will get a serialization error.
To avoid that, use the default READ COMMITTED isolation level.
At the time of backup firebird database (gbak -g -ig) I have the following error:
gbak: writing data for table ORDERS
gbak: ERROR:message length error (encountered 532, expected 528)
gbak: ERROR:gds_$receive failed
gbak:Exiting before completion due to errors
When I'm using gfix with different parameters (-v -full, -mend, -ignore), I have the message:
Summary of validation errors
Number of index page errors : 540
In firebird.log file I see the lines:
PC (Server) Thu Sep 20 08:37:01 2018
Database: E:\...GDB
Index 2 is corrupt on page 134706 level 1. File: ..\..\..\src\jrd\validation.cpp, line: 1699
in table COMPONENTS (197)
However, the database works OK without problems.
Please help me to fix the error and make a backup.
(I need the backup to migrate to on 64bit server).
I am trying to build a report in tableau desktop 9.3.2 with mongodb (live connection). I using the simba odbc driver for mongodb. I trying to join tables but I keep getting errors if I perform more than one joins and also I cannot do anything other than an inner join. It gives the following errors:
[Simba][MongoDBODBC] (110) Error from MongoDB Client: Failed to read 4 bytes from socket within 300000 milliseconds. (Error Code: 4)
[Simba][MongoDBODBC] (110) Error from MongoDB Client: Corrupt or malicious reply received. (Error Code: 14).
It is not even taking 5 minutes, it gives the error immediately. I was working with some sample data(around 1000 documents) and it worked fine. But now I have 800MB of data. Is it too much data?
Also When I create data source filters and do update now it give me an error:
[Simba][MongoDBODBC] (110) Error from MongoDB Client: Failed to read 262250 bytes from socket within 300000 milliseconds. (Error Code: 4)
Does anyone know what the problem is and how I can resolve it?
Im running a workflow in powercenter that is constatnly getting an SQL1224N error.
This process execute a query against one table (POLIZA) with 800k rows, it retrieves the first 10k rows and then it start to execute to another table with 75M rows, at ths moment in DB2 an idle thread error appear but the PWC process still running retrieving the 75M rows, when it is completed (after 20 minutes) the errros comes up related with the first table:

I have a similar process runing against the same 2 tables and it is woking fine where the only difference I can see is that the DB2 user is different.
Any idea how can i fix this?
Regards
The common causes for -1224 are:
Your instance or database has crashed, or
Something/somebody is forcing off your application (FORCE APPLICATION or equivalent)
As for the crash, I think you would know by know. This typically requires a database or instance restart. At any rate, can you please have a look into your DIAGPATH to check for any FODC* directories whose timestamp would match the timestamp of the -1224 errors?
As for the FORCE case, you should find some evidence of the -1224 in db2diag.log. Try searching for the decimal -1224, but also for its hex representation (0xFFFFFB38).
while taking a backup from my PostgrSQL Database

i have googled but dint get any solution to solve this
It means, so your data file is corrupted - a solution is relative difficult - the best way is recovery from some older backup. You can try to fix it with replacing broken data page by zeroes - but you lost some data, and without some deeper knowledgeable you can destroy more than now it is.
