Hello everyone,
I have a 5gb rpt file.
Rpt file content is as follows:
(base) skoc@skoc ~ % head -5 '/Users/skoc/postgresql/lx/lxRo.rpt'
lxOid|lxFlags|lxType|lxFromLat|lxFromId|lxToLat|lxToId|lxCrDate|lxRelRul|lxModDate|lxOwner|lxAltOwn1|lxAltOwn2|lxTenant|lxDOV|lxIOV|lxToType

Delimiters is “|”
Current posttgresql version:
PostgreSQL 16.2 on x86_64-apple-darwin20.6.0, compiled by Apple clang version 12.0.5 (clang-1205.0.22.9), 64-bit
plm=# show work_mem;
work_mem
----------
16MB
(1 row)
I created a table with the following command.
CREATE TABLE IF NOT EXISTS public.lxbo
(
c1 serial NOT NULL,
c2 jsonb NOT NULL,
CONSTRAINT lxbo_pkey PRIMARY KEY (c1)
)
The process I want to do:
insert the data whose content is specified above into column c2 in jsonb format.
1-How should the rpt file content be converted to jsonb format?
2-What is the way to import the relevant jsonb file into the table I specified?
3-Do I need to update the work_mem value and/or any other value?
Thanks
