Pgloader 3.6.2 - "on error resume next" functionality doesn't work for Pgloader.
bhanase opened this issue · comments
Hi Team,
While migrating Postgres.v11–v14, we found the following query issue with the internal PGloader 3.3.2 tool. As a result, we upgraded to PGLoader 3.6.2.
Following that, we encountered issues when loading from CSV files using the PGloader, and the job immediately ceased executing as a result of the error (contains ""). We attempted to proceed with the procedure by using the on error resume next command, but PGLoader version 3.6.2 is not allowing this command to function as intended.
While we can process the entire CSV file after an error occurs in PGloader version 3.3.2 with Postgres-v11, this feature is not supported in PGloader version 3.6.2 with Postgres-v14.

The code below is for the on error continue next in PGloader load.csv, but it does not support the below WITH instructions when loading the CSV with the sample field ("OBC ZONE5- AREAN "N" ", ""MUSAFFAH INDUSTRIAL AREA,M 24Ï¿½""), specifically (""). Instead, it stops while loading the data.
