DSS added to handle merges with lower versions of Postgres
Resolved in Pega Version 8.7.1
After update, executing the batch campaign with volume constraint resulted in the second data flow DF_Wait failing with error message "ERROR: number of columns (1844) exceeds limit (1664)". This was due to the database set’s change (in 8.5) to use the database layer’s merge statement. Prior to that, the logic used "deletes and inserts". Depending on the version of Postsgres, the generated SQL statement for a merge statement is different. The “INSERT … ON CONFLICT … UPDATE” syntax is generated for Postgres 9.5+ AND when there is a PK constraint defined for the DB table. Otherwise, the complex UPSERT statement (old syntax) is generated, as was the case in this issue. This is a known issue in the Postgres server software where it mis-interprets the number of columns involved. i.e., it mistakenly counts the number of columns twice. As a result, the actual maximum columns allowed is only half of the official limit (1664). The same UPSERT statement does not cause the “exceeds limit” exception if there are 832 or fewer columns in the statement. To resolve this, an option has been provided to select between the “original logic” (deletes and inserts) and the “merge statements” logic by way of the DSS “decision/datasets/db/useMergeStatementForUpdates”. Setting “true” will use the merge statement logic, and setting “false” will use deletes and inserts. When the DSS is not defined, the default is "true" and the system will use merge statements in the form preferred by Postgres 9.5+.

Check added to disable offset support for older versions of Oracle
Resolved in Pega Version 8.7.1
An ORA-00933 error was generated after upgrading from Pega 7.1 to Pega 8.5. This was traced to a conflict between Oracle 11g and the Pega 8.5 platform related to an OFFSET statement being added to a query for a version of Oracle that doesn't support it. The preferred solution is to upgrade Oracle to address this, but in order to support backwards compatibility a check has been added which will disable offset support in Oracle if productversion <=11.

Handling added for missing expose.accessGroup property
Resolved in Pega Version 8.7.1
After exposing an existing page group and page list properties along with single value properties using a declare index, running the Column Populator tool prpcServiceUtils to populate the historical data resulted in the single value properties being updated in the exposed column properly, but the page group and page list properties were not updated in the declare index table. On new case creation the declare index tables were updated. This was traced to the default expose.accessGroup not being set for the user, and has been resolved by adding a check and handling that will add the missing property in prpcserviceutils.properties defining the access group for the Rule-Declare-Index of the classes being exposed if it is not present.

Inline images retrieved for deferred-load email
Resolved in Pega Version 8.7.1
When emails were defer-loaded, inline images with code entered into the non-cache section in pyExtractHtmlFromAttachment were not being displayed. This has been resolved by passing the current page parameter to pyExtractHTMLFromAttachment to convey the pyID.

Added API for Pega Call Team websocket reconnect
Resolved in Pega Version 8.7.1
When a call came in, the operator was not able to pick it up due to the popup only containing a reconnect section. This has been resolved by adding the disconnectAndReconnect API which will be used by Pega Call Team if the websocket reconnect limit exceeds 5.

Added deferred loading for email cases
Resolved in Pega Version 8.7.1
When there were a significant number of email interactions on an email case, delays were seen when loading the case in the UI. Investigation traced this to a high number of database calls along with the BLOBs also being open. To improve performance, the new rule pyDeferLoadEmails has been added which toggles the UI and loads emails faster. In addition, the button label has been modified to read "View all emails" in place of "Show all" while defer load is enabled.
