> Is PostgreSQL SQL database command syntax similar to MySQL/MariaDB?
If you stuck to "standard SQL" in Mysql, you'll generally be fine; the differences will be pretty minor. The further
youstrayed from the standard will cause you more work -- usually. That being said, moving for any DB to another will
alwayscause you to find DB-specific things. Of course, there are always a few things that can only be done with
DB-specificcode, so you'll be rewriting those parts with certainty (an example is the insert-or-update concept).
[Side note: I forced myself to read a good part of the SQL standard some time back and was amazed by how many times the
phrase"implementation defined" was used, which helps to explain why all the DBs do some things so differently.]
The admin commands are quite different as well, be prepared for that, but I can't think of anything that Mysql can do
thatPg can't as well. (Although it's been awhile since I had to use Mysql, so I may have forgotten something.)
Last but not least, please remember that all of those "unusual" things you had to do to get Mysql to work, or work
aroundits bugs, won't be needed and will more than likely get in your way with Postgresql. I'm not saying the Pg is
perfect,but that Mysql's bugs and oddities don't apply to Pg.
Good luck with your conversion and welcome to Pg!
