# File Name: pg_match.py
# Description:
# This file is a python script file which compares 2 schemas for data consistency.
# It is functional for Postgresql only at this time. It is totally rewritten using psycopg2 module instead of pgdb module.
#
# External Interfaces: Postgresql databases (normally master and slave) # # Assumptions:
# 01. Functional for Postgresql databases at this time.
# 02. Assumes the secret database credentials file (.dbcompare) is populated correctly.
#
# usage:
# type = simplescan | detailedscan
# pg_match.py -t simplescan -H localhost --Sport 5414 --Suser postgres --Sdb clone_testing --Sschema sample --Thost localhost --Tport 5414 --Tuser postgres --Tdb clone_testing --Tschema sample_clone1
# pg_match.py -t simplescan -H eddp-staging-popstore3.cluster-cddj9wcflvor.us-gov-west-1.rds.amazonaws.com --Sport 5432 --Suser root --Sdb popstore3 --Sschema lookup_module --Thost eddp-staging-popstore3.cluster-cddj9wcflvor.us-gov-west-1.rds.amazonaws.com --Tport 5432 --Tuser root --Tdb popstore3 --Tschema lookup_module_beta
# Assumptions:
# 1. Only supports PG versions 10 and up.
# 2. Both versions must be v10 if either one of them is v10.
# 3. Python 2.7+, 3.x+ are supported python versions.

#
# Modifications History:
# Date Programmer Description of Change
# ========== ========== =====================
# 2013-11-29 Michael Vitale Original Coding
# 2014-06-26 Michael Vitale Ported to Postgresql: big problem-->information_schema.tables does not have a table_rows column!
# 2016-07-02 Michael Vitale Major rewrite: Changed name from pg_comparedatabases.py to pg_match.py
# procedural to object oriented, i.e., class instantiation
# changed logic for what gets done for rowcounts: compare pg_class.reltuples, pg_stat_user_tables.n_live_tup, then actual count if necessary
# 2022-05-29 Michael Vitale version 2.0: Major rewrite. Made compatible with python 2.7 and 3.x
# 2022-06-12 Michael Vitale version 2.1: Make backward compatible with v10 (pg_proc.prokind)
# 2022-06-14 Michael Vitale version 2.1: Added view check. Fixed table/view check by adding join to information_schema.tables. Detailed table check.
# 2022-06-17 Michael Vitale version 2.1: Change detailedscan to mean real rowcounts.
# 2022-06-19 Michael Vitale version 2.1: Add logic for comparing keys and indexes.
# 2022-09-01 Michael Vitale version 2.2: Replace pg_auth with pg_roles to be compatible with PG cloud services. Fixed formatting to allow for longer names.
# 2023-01-02 Michael Vitale version 3.0: Added logic for funcs/procs diffs.
# Fixed column comparison for column differences, not attribute ones which are handled correctly.
# Fixed column attribute slowness
# 2023-01-13 Michael Vitale version 3.1 Fixed logic for handling cases where no objects found in a particular class
# 2023-01-18 Michael Vitale version 3.2 Enhancement: add bypass columns parm, inplace updates for row counts during DetailedScan, added signal handler for ctrl-c interruptions
