Subject: migration: remove mandatory index drops from 127 because of potential fatal errors... 
X-Git-Tag: 16.3~359
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=89e31b9d4e721da222d3fbb5e66b0c6a18961ac9;p=tt-rss.git

migration: remove mandatory index drops from 127 because of potential fatal errors; remove unnecessary named indexes from mysql schema for fields with foreign key constraints (mysql should create indexes automatically on table creation for those fields)
