Hi team,

I am trying to migrate the data from db2 to postgreSQL in which one of the table is having XML data.

For one of the file (13MB) I'm facing an error with 

ERROR: invalid XML content

Detail: line 418061: internal error: Huge input lookup

nested exception is org.postgresql.util.PSQLException: ERROR: invalid XML content

I even tried with more size of XML data (30MB) but for this case I can able to migrate the date successfully.

But only for that file I'm facing the issue.

Later, I got to know that there are some special characters in that file not sure whether this can be the issue or not.

I'm using java.sql.preparedstatement

Preparedstatement.setSQLXML(iterator, xmlobject) to migrate the data from db2 to postgreSQL

When I tried in my local postgreSQL (which is windows and located in APAC region. I can able to migrate successfully)

But when I'm trying to migrate into azure postgreSQL (Linux OS, located in Germany) facing an issue.

That sounds like it has to do with locale differences between the two systems.

Exactly what Pg version (including patch level) and locale are in each of the two systems?

Even if it's not that, something is configured differently between the two systems.

I would install 14.7 on your Windows box (multiversioning is supported, at least on Linux; probably Windows too), making sure that it uses the en_US.utf_8 locale (or the closest Windows analog).  Then I'd try the same migration on the Windows box.

After all development boxes should run the same software version as production...

Thank you for the reply.

The pg version is 14.7 (Azure DB)

Locale :-

LC_COLLATE & LC_CTYPE : en_US.utf_8

Local postgreSQL:- Version:- (15.1-1-windows-x64-binaries)

LC_COLLATE & LC_CTYPE:-

English_United States.1252

Please let me know if any other information is needed.

Thanks & Best Regards,

Sai Teja
