TRAP: FailedAssertion("HaveRegisteredOrActiveSnapshot()", File: "toast_internals.c", Line: 670, PID: 19403) - Mailing list pgsql-hackers

Hi,

On master I got a FailedAssertion("HaveRegisteredOrActiveSnapshot()"
on an assert-enabled instance and with (I think) data over a certain length.

I whittled it down to the attached bash (careful - it drops stuff).  It 
has 5 tsv-data lines (one long line) that COPY slurps into a table.  The 
middle, third line causes the problem, later on.  Shortening the long 
line to somewhere below 2000 characters fixes it again.

More info in the attached .sh file.

If debug-assert is 'off', the problem does not occur. (REL_14_STABLE 
also does not have the problem, assertions or not)

thanks,

Erik Rijkers
