Dear pgsql:
When we adding a custom system table and defining an index for it at the
same time, the code compilation is possible, but the following errors may
occur when starting the database:
----------------------------------------------------------------------------------------------------------
fixing permissions on existing directory /usr/local/pgsql/data ... ok
creating subdirectories ... ok
selecting dynamic shared memory implementation ... posix
selecting default max_connections ... 100
selecting default shared_buffers ... 128MB
selecting default time zone ... Asia/Shanghai
creating configuration files ... ok
running bootstrap script ... 2023-07-19 09:40:47.083 CST [2808392] FATAL:
operator class "key_ops" does not exist for access method "btree"
2023-07-19 09:40:47.083 CST [2808392] PANIC: cannot abort transaction
1, it was already committed
Aborted (core dumped)
child process exited with exit code 134
initdb: removing contents of data directory "/usr/local/pgsql/data"
---------------------------------------------------------------------------------------------------------------
There are my steps as follows:
1. add a new header file (pg_bm_client_global_keys_args.h) for the
custom system table, the file path is :*
src/include/catalog/pg_bm_client_global_keys_args.h;*
2. the modified Makefile is: *src/backend/catalog/Makefile, *add the new
header file at the label *CATALOG_HEADERS *of the file;
3. make; make install
4. when run the cmd :* /usr/local/pgsql/bin/initdb -D
/usr/local/pgsql/data, *the error will occur*.*
This problem has been bothering me for a long time. Can you help me solve
it？
Best Wishes.
