Commit Message

Fix "index row size exceeds maximum" when building index on compressed toasted data

CREATE INDEX on a column containing existing PGLZ/LZ4-compressed data fails with index row size N exceeds orioledb maximum 2688, while inserting data into a pre-existing index on the same column works fine.

Root Cause
o_get_tbl_att() calls PG_DETOAST_DATUM on all VARATT_IS_EXTENDED values, which includes inline compressed varlenas. During build_secondary_index_worker_heap_scan, this decompresses stored PGLZ values back to their full size (e.g., 10000 bytes), blowing past the index tuple size limit.
