Hi,
I am trying to run postgresql functions with threads by using OpenMP. I tried to parallelize slot_deform_tuple function(src/backend/access/common/heaptuple.c) and added below lines to the code.
#pragma omp parallel
{
#pragma omp sections
{
#pragma omp section
values[attnum] = fetchatt(thisatt, tp + off);
#pragma omp section
off = att_addlength_pointer(off, thisatt->attlen, tp + off);
}
}
During ./configure I saw the information message for heaptuple.c as below:
"OpenMP defined section was parallelized."
Below is the configure that I have run:
./configure CC="/path/to/icc -openmp" CFLAGS="-O2" --prefix=/path/to/pgsql --bindir=/path/to/pgsql/bin --datadir=/path/to/pgsql/share --sysconfdir=/path/to/pgsql/etc --libdir=/path/to/pgsql/lib --includedir=/path/to/pgsql/include --mandir=/path/to/pgsql/man --with-pgport=65432 --with-readline --without-zlib
After configure I ran gmake and gmake install and I saw "PostgreSQL installation complete."
When I begin to configure for initdb and run below command:
/path/to/pgsql/bin/initdb -D /path/to/pgsql/data
I get following error:
The files belonging to this database system will be owned by user "reydan.cankur".
This user must also own the server process.
The database cluster will be initialized with locale en_US.UTF-8.
The default database encoding has accordingly been set to UTF8.
The default text search configuration will be set to "english".

I could not get the point between initdb process and the change that I have made.
I need your help on solution of this issue.
Thanks in advance,
Reydan
