mmustafasenoglu opened a new pull request, #2469:
URL: https://github.com/apache/age/pull/2469
## Summary
Closes #2449
Both load_labels_from_file and load_edges_from_file relied on PostgreSQL
COPY's default comma delimiter, causing silent data corruption on labels and
segfault on edges when using non-comma-delimited files.
This adds an optional delimiter TEXT parameter (default comma) to both
functions, allowing users to specify the field separator.
## Changes
- create_copy_options() in both ag_load_labels.c and ag_load_edges.c now
accepts and passes the delimiter to COPY
- SQL function signatures updated with new delimiter parameter (default
comma)
- Regression tests added for pipe-delimited vertex and edge files
## Usage
-- Pipe-delimited vertex file
SELECT load_labels_from_file('graph', 'Label', 'file.csv', true, false,
'|');
-- Pipe-delimited edge file
SELECT load_edges_from_file('graph', 'Edge', 'file.csv', false, '|');
## Backward Compatibility
The new parameter has a default value of comma, so all existing calls
continue to work without changes.
