ERROR 1146 (42S02): Table 'performance_schema.session_variables' doesn't 
exist

But it should be mysql-5.7.24 if I can believe the mysql shell startup text 
and my package manager:

5.7.24(0/18)(22:57:44 20-11-18)(server -cjk -client-libs -cracklib -debug 
-experimental -jemalloc -latin1 -libressl -numa -perl -profiling -selinux 
-static -static-libs -systemtap -tcmalloc -test -yassl …

But perhaps I should enable some of those flags with a - in front?

This is possibly related to something I asked about a good two years ago:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual 
that corresponds to your MySQL server version for the right syntax to use 
near 'current_timestamp()' at line 1

Query OK, 0 rows affected (0,17 sec)
Records: 0  Duplicates: 0  Warnings: 0

And in the 

show create table pimitemtable;

result I see

`atime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,

+---------------------+
| CURRENT_TIMESTAMP() |
+---------------------+
| 2018-12-11 23:06:45 |
+---------------------+
1 row in set (0,00 sec)


And…

mysql> alter table pimitemtable modify column remoteId varbinary(1024);    
Query OK, 43524 rows affected (1,98 sec)
Records: 43524  Duplicates: 0  Warnings: 0

Hurray!
