function Get-DbaPbmStore {
    <#
        .SYNOPSIS
            Returns the policy based management store.
 
        .DESCRIPTION
            Returns the policy based management store.
 
        .PARAMETER SqlInstance
            SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
        .PARAMETER SqlCredential
            Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
        .PARAMETER Policy
            Filters results to only show specific policy
 
        .PARAMETER Category
            Filters results to only show policies in the category selected
 
        .PARAMETER IncludeSystemObject
            By default system objects are filtered out. Use this parameter to include them.
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
