Benjamin Richter commented on SOLR-9256:
----------------------------------------
This could be caused by postgres limitations. Postgres only allows one open
resultset per connection. Recent changes to JdbcDataSource.java optimized
connection reusing and resultset closing.
> Solr 6.x DataImportHandler fails with postgreSQL dataSource with multiple
> joined entities
