Changelog

Date updated / Software version / SQLite DB schema version

Use min of start time and max of total time of parallel leader and all workers, instead of just showing the parallel leader durations, for calculating operator durations
Set CTE operator to use CTE Scan icon
Updated operator time difference calculations
Updated operator exclusive time calculations
Updated plan list font
Fix: stop highlighting parallel leader when operator's time difference = 0
Fix: corrected worker actual mass calculation
Fix: corrected parallel leader time difference highlighting issues
Removed exclusive time from workers

Fix: Actual and estimated "rows removed by filter/index recheck" counts
Added db columns for sort workers (for a future version)
Checked many calculations for rows, mass, workers, and filters for this release on multiple PG versions (9.3, 9.6, 10, 12, 12.1)

Improved estimated "rows removed by filter/index recheck" count
Add: When using slider, darken completed operators
Fix: Plan stats are available w/o changing to a different plan first
Add: Merge anti-join icon

Use black text where plan width = 0 (indicate when operator returned no data)
Numerous bug fixes (main reason for update)

Add: Remember password checkbox
Add: Prompt to ask for password
Top buttons are more closely tied to plan graph view (e.g. if there are no actual rows in the JSON plan, Actual Rows, Actual Mass, and both Ratio buttons are disabled; if there are no actual times, Exclusive Time and Time Difference buttons are disabled)
Disable Cost slider if there are no costs
Disable Time slider if there are no times
Fix: Exceptions would occur when switching between costs on and off
Fix: Long-running SQL code bug fix (re: calculating # of loops recursively)
Fix: Toggling workers then zooming would size boxes wrongly
Removed % by Disk and RAM buttons
Removed % by Disk and RAM worker info
If user deleted all plans, disable Delete and Duplicate buttons
