We might face error like "ERROR 1153 (08S01) at line 25247: Got a packet bigger than 'max_allowed_packet' bytes" while importing database in MySQL/MariaDB. Sometimes error message may be like "ERROR 2006 (HY000) at line 25247: MySQL server has gone away". It happens when the database dump file is having SQL INSERT statements with long lines of data.
Sometimes we will come to situations where we want to print error messages directly to stderr (Standard Error stream). Most probably when we are writing CLI applications. Users can direct program output to a text file but we need to show the error messages always in terminal.
