Re: Recently-introduced segfault in initdb?

OK, I must have done something wrong with the bisect the first time. Now
I'm getting the following as the problem commit:

fd1a421fe66173fb9b85d3fe150afde8e812cbe4 is the first bad commit

Add prokind column, replacing proisagg and proiswindow

The new column distinguishes normal functions, procedures, aggregates,

and window functions. This replaces the existing columns proisagg and

proiswindow, and replaces the convention that procedures are indicated

by prorettype == 0. Also change prorettype to be VOIDOID for
procedures.

bisect run success

When it's not working, I get the following output from initdb:

"ijmorlan".

This user must also own the server process.

The database cluster will be initialized with locale "C".

The default text search configuration will be set to "english".

Data page checksums are enabled.

initdb: removing data directory "./test/pgdata"

I hope this is more helpful.
