Hackers,
Head of master is giving me a segfault on running ANALYZE when isolation mode is SERIALIZABLE.
My configure:
export CFLAGS="-g"
export LDFLAGS="-L/usr/local/opt/readline/lib"
export CPPFLAGS="-I/usr/local/opt/readline/include"
./configure \
--prefix=/Users/joe/Development/tmp/pg \
--enable-cassert \
--enable-debug \
--with-readline
To reproduce:
[joe@oberon pg]$ ./bin/initdb -D $(pwd)/data
The files belonging to this database system will be owned by user "joe".
This user must also own the server process.
The database cluster will be initialized with locale "en_GB.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

initdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
./bin/pg_ctl -D /Users/joe/Development/tmp/pg/data -l logfile start
[joe@oberon pg]$ ./bin/pg_ctl -D /Users/joe/Development/tmp/pg/data -l logfile start && ./bin/psql -d postgres
waiting for server to start.... done

psql (12devel)
Type "help" for help.

server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
