.EXAMPLE
Get-DbaEstimatedCompletionTime -SqlInstance sql2016
     
Gets estimated completion times for queries performed against the entire server
     
.EXAMPLE
Get-DbaEstimatedCompletionTime -SqlInstance sql2016 | Select *
     
Gets estimated completion times for queries performed against the entire server PLUS the SQL query text of each command
 
.EXAMPLE
Get-DbaEstimatedCompletionTime -SqlInstance sql2016 | Where-Object { $_.Text -match 'somequerytext' }
     
Gets results for commands whose queries only match specific text (match is like LIKE but way more powerful)
 
.EXAMPLE
Get-DbaEstimatedCompletionTime -SqlInstance sql2016 -Database Northwind,pubs,Adventureworks2014
 
Gets estimated completion times for queries performed against the Northwind, pubs, and Adventureworks2014 databases
