Howdy folks,
Doing some testing with 8.5alpha3, my standby crashed this morning whilst
doing some testing. Seems I have a core file, so thought I would send a report.
Version: PostgreSQL 8.5alpha3 on i386-pc-solaris2.10, compiled by GCC gcc
(GCC) 3.4.3 (csl-sol210-3_4-branch+sol_rpath), 32-bit
Error in the log was simply this:
LOG: restored log file "000000010000000300000032" from archive
LOG: startup process (PID 385) was terminated by signal 11
LOG: terminating any other active server processes
info from core file was:
postg...@postgresdev[/export/home/postgres/pgwork/data/slave]dbx
/export/home/postgres/pgwork/inst/slave/bin/postgres core
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.6' in your
.dbxrc

DatabasePath = (nil)
Theo mentioned that he expects the above would work under Linux, but that we
need DatabasePath to not be null in the above.
FWIW, the SQL I was running on the master did involve two create database
commands back to back.
LMK if you have any questions.
