# PostgreSQL Antivirus/EDR Exclusion Guidance for ManageEngine OpManager

## Purpose

This document provides guidance for customers using ManageEngine OpManager whose bundled PostgreSQL database may be impacted by third-party Antivirus (AV) or Endpoint Detection and Response (EDR) tools.

Such tools can sometimes interfere with PostgreSQL binaries, data directories, or services, which may result in:

- Product startup failures
- Slower performance during database operations
- Errors during service pack or patch installations

**Note:** This document should only be followed if the customer is experiencing issues caused by AV/EDR interactions with PostgreSQL-related components.

## When to consider exclusions

Customers are advised to consider excluding PostgreSQL folders from AV/EDR scanning in the following scenarios:

- Product startup failures with errors indicating PostgreSQL binaries are missing or blocked.
- PostgreSQL service fails to start or initialize during application startup.
- Service pack or patch installation fails due to missing or quarantined PostgreSQL binaries.
- Database startup or query execution is noticeably slow, and AV/EDR activity is suspected.
- Logs or AV/EDR reports show detection, quarantine, or deletion events for PostgreSQL components bundled with the product.

## Recommended exclusions

If AV/EDR is confirmed to interfere with PostgreSQL, exclude the following path from real-time and scheduled scans:

```
<product home>/pgsql/
<product home>/pgsql/bin/postgres.exe
```

**Note:** Replace `<product home>` with the actual installation path of ManageEngine OpManager on the target system.

## Disclaimer and liability acknowledgment

By applying these exclusions, the customer acknowledges:

- Exclusions are recommended only to resolve known compatibility or performance issues caused by third-party security tools.
- It is the customer's responsibility to evaluate the risks and apply these exclusions based on their internal security policies and threat model.
- ManageEngine OpManager does not assume liability for any security risk introduced by applying AV/EDR exclusions.
