I'd really like PostgreSQL to somehow warn me when I start doing things
like this. It's not my intent to use PostgreSQL-specific SQL in general
so when I start doing it I'd like to know. In some cases there may not
be an option, of course, but especially in cases where there's a 'right
way' I'd love for PostgreSQL to spit out a warning which tells me what
the right way is.
ie: "select * from table_name where column_name != '1';"
Warning: '!=' is not valid SQL, use '<>' instead.
This would help me, at least, write correct and portable SQL. :)
